| Assoc Prof Alfred Tok Iing Yoong | 1) Carbon-based Field-Effect Transistor Sensors
The biosensors market, which is currently at USD 9.9 billion, is expected to reach USD 18.9 billion in 2019 (GIA Report, 2014) propelled by the growing population and health issues. Our group capitalizes on this emergent market and researches on disposable and low-cost sensor suitable for real-time sensing in field conditions. Our group focuses on sensors for biological and gas detection applications.
2) Synthesis of Nanostructured Materials using Atomic Layer Deposition (ALD)
Atomic layer deposition (ALD) has evolved to be a unique tool for nanotechnology with atomic level control of the depositions, 3D conformity and homogeneity. Film depositions can be realized for complex non-planar topographies for a wide range of applications such as energy conversion and storage, nanoparticle catalysts, nanostructures for drug delivery, gas separations, sensing, and photonic applications. Our group focuses on ALD materials for solar cell, hydrogen generation and smart window applications.
3) Hard & Tough Materials for Ballistic Protection Application
The next generation of military vehicular and soldier system requires light-weight materials with high strength-to-weight ratio. Our research focuses on the synthesis and densification of nanostructured materials & desired composite architecture to significantly raise the ballistic protection capability. The B-C-N-O group of compounds are potential candidates to form novel materials for ballistic protection application as they inherent the unique properties from both boron nitride and boron carbide which are known for their light weight, high hardness, low friction coefficient and high wear resistance. Prof Tok leads a team of collaborators in armour material research ranging from high temperature synthesis of novel superhard materials and consolidation by state-of-the-art Spark Plasma Sintering to advanced characterisation techniques such as depth of penetration test using Two-Stage Light-Gas Gun.
4) Institute for Sports Research
Our group is involved in the Institute for Sports Research, working on the damping property of midsoles which is based on carbon nanotube (CNT). CNT’s high aspect ratios (length/diameter) is particularly desirable for mechanical reinforcement, and it is found that the vertical aligned (VA)CNTs perform well in damping, to dissipate the energy absorbed under compression (Figure 7). Our present job is to tune the damping property of VACNT by adjusting the length, diameter and area density etc. parameters and try to reinforce the polymer with VACNT to fabricate midsole material with better cushion property.
5) NRF-CREATE
In accordance with the objectives of the Energy Thrust Program of the NRF-CREATE Project, our group is focused on the design and synthesis of highly functional nanomaterials, which enables energy harvesting and conservation. Recently, novel graphene oxide synthesized nanoballs and nanoflowers were synthesized. These exhibit potentials for supercapacitors and energy applications. In general, these activities results in above 50 publications, 17 patent applications and projects discussions with companies regarding commercialization possibilities. |

| Prof Bo Gunnar Liedberg | The research interests of Prof. Bo Liedberg can be divided into three main areas
Surface Chemistry and Self Assembled Monolayers
This part of the research concerns fundamental studies of adsorbates and ultrathin molecular architectures, like Self-Assembled Monolayers (SAMs), on solid supports. The group was very early in studying self-assembly of substituted alkylthiols on gold substrates. A key activity has been to study temperature driven phenomena occurring in such assemblies as well as in adsorbed layers on top such SAMs. Oligo(ethylene glycol) and oligosaccharide SAMs have attracted considerable attention, both experimentally and theoretically, because of their structural characteristics and advantageous properties in contact with biofluids. Another area concerns interfacial water and ice. Temperature programmed studies have been undertaken to improve the understanding of the nucleation and microscopic wetting behavior of water/ice. The complexity of the SAMs has increased over the years and we are today focusing on architectures based on SAMs bearing multivalent chelator heads, helix-loop-helix polypeptides and receptor functions.
Bioinspired and Biomimetic Nanoscience
This research concerns the development of nanoscale architectures fabricated using either top-down or bottom-up protocols (or a combination of both). We are, for example, developing plasmonic arrays based on 100 nm gold nano dots on silicon and glass surface for amplification of optical fluorescence signals, so-called metal enhanced fluorescence (MEF). We are also developing composite materials based on a combination of de novo designed peptide scaffolds, planar surfaces and nanoparticles of controlled size and shape. A novel concept based on peptide folding has been used for controlled assembly of gold nanoparticles. The group is also involved in the development of Dip Pen Nanolithography (DPN) for patterning of surfaces on the 30-100 nm length scale. This work is performed jointly with a previous student of the group who nowadays is setting up a nanolaboratory at the Institute of Physics, Vilnius. We are also involved in several EC projects where different types of micro- and nanoscale patterning tools are employed for production of coatings for biofouling, sensing and biomedical applications.
Optical Biosensors, micro- and nanoarrays
The group has a long experience in developing optical transducers for biosensing application. We were the first to demonstrate the use of surface plasmon resonance for studies of bioaffinity interactions at surfaces, a technology that today form the backbone in SPR/Biacore instruments developed for biospecific interaction analysis (BIA). We are today using it in combination with ellipsometric interrogation and imaging optics for microarraying, and in combination with nanoparticle for studies optical enhancement phenomena. This includes, for example, microarray chips for protein multiplexing. The group is also working on the development of generic biochips for studies of ligand-receptor binding. Besides working on microarray fabrication for protein detection and analysis we are also developing biochips for the safety and security area.

Despite advances in therapeutic drugs and tools, much work remains towards the early identification and eradication of infectious diseases. We are developing model membrane sensing platforms to interrogate the mechanisms of virus life cycles, especially that of the Hepatitis C virus (HCV). We are also leveraging these engineering strategies to combat a wide range of viruses including dengue and influenza. In a related project, we are characterizing the molecular interactions of phospholipases involved in inflammatory response and the pathogeneses of many cancers.
To more effectively translate new medicines into clinical therapies, we also have an active regenerative medicine team focused on liver tissue engineering. The liver is an important organ that is the site of HCV infection. Moreover, liver toxicity is a major challenge which accounts for the costly failure of many drugs late in the pipeline. Therefore, our primary aim in this area is to develop an artificial liver tissue platform to study HCV infection and drug toxicity.
Taken together, our overall research initiative seeks to engineer artificial membrane and tissue platforms to probe biological systems, and to translate these findings into enhanced therapeutic and drug delivery options that more effectively target infectious diseases, inflammatory disorders, and cancer. |

| Assoc Prof Ling Xing Yi | The research programs in our laboratory combine chemistry, nanotechnology, and materials science approaches to develop functional nanostructures with novel catalysis, plasmonic and sensing applications.

Nanostructures for optimal solar energy conversion
The amount of solar energy striking the earth’s surface in one hour is enough to power human activity for one year. Hence, solar energy provides one of the best options to sustain human civilization. An efficient photosystem is able (1) to absorb a large amount of broadband solar energy at full solar spectrum, (2) convert photons into electron-hole pairs efficiently, and (3) perform catalysis reaction to produce fuel at high yield. Currently, most photocatalysts suffer from low reaction efficiency. The main goal in this project is to design nanostructures with artificial photosynthesis properties to achieve high solar fuel conversion. Our strategy is focused on fabricating well-defined nanostructures by combining bottom-up self-assembly and top-down nanofabrication techniques. Important information will be gained to drive the solar-to-fuel photocatalysis towards commercialization and to reduce human’s dependence on non-renewable fossil fuel. |

| Assoc Prof Loo Say Chye Joachim | I. Particulate Systems as Drug Carriers
A range of biocompatible materials (i.e. PLGA and hydroxyapatite) are synthesized as microparticles and/or nanoparticles for drug delivery. In this work, we have synthesized multi-layered particles with drug localization at different layers. The aim is to control the release of drugs by altering particle size, layer thickness and other particulate parameters. On the same platform, mesoporous bioglass and hydroxyapatite are also synthesized to release therapeutic proteins.
II. Targeted Delivery of Hybrid Particles for Osteomyelitis
Osteomyelitis, or bone infection, is currently treated through systemic delivery of antibiotics over a period of time.

| Asst Prof Lum Guo Zhan | The three main research topics in our lab are: 1. shape-programmable millimeter-scale robots, 2. gallium and 3. flexure mechanisms for high precision applications.
1. Shape-Programmable Millimeter-scale Robots
Shape-programmable robots are machines that can be excited by external stimuli to generate desired time-varying shapes. These robots are especially appealing at small-scale because they have great potential to achieve functionalities unattainable by their rigid counterparts.
As these miniature soft robots can easily access confined spaces within the human body, they show great promise to realize revolutionary biomedical applications such as targeted drug delivery and minimally-invasive surgeries. While there exists many different types of actuation, here we are particularly interested in using remote magnetic fields to control our robots. In contrast to other methods, magnetic actuation offers higher control authority as the actuating fields can be controlled not only in their magnitude but also in their direction and spatial-gradients. Furthermore, this actuation method will be compatible for our targeted medical applications as the actuating magnetic fields can easily and harmlessly penetrate through biological tissues.
Heading towards these biomedical applications, we have previously developed a universal design method that can program the magnetization profile and actuating fields for our robots to achieve their specified functionalities. However, to enhance the practicality of these robots, we will continue to develop new design methods to further enhance their functionalities.
2. Gallium
Gallium is a class of liquid metal that can be attached to millimeter-scale robots to enhance their functionality. In our previous research, we discovered that gallium can exhibit highly reversible and switchable adhesion when it undergoes a solid–liquid phase transition. It has been demonstrated that this liquid metal can become highly adhesive when it freezes and it can conversely lose its adhesion when it melts. These adhesive properties had been characterized, and we experimentally show that gallium has good performance over a wide range of smooth and rough surfaces, under both dry and wet conditions.
Another critical advantage of gallium is that it has a natural layer of oxide, which acts like an elastic membrane surrounding the liquid metal. This oxide layer can effectively conserve the mass of gallium when it is in the liquid-state, and this in turn ensures that gallium can be used repeatedly as a reversible and switchable adhesive. The unique adhesive properties of gallium can therefore allow it to perform various pick-and-place tasks at small-scale, which are critical for numerous applications in transfer printing, robotics, electronic packaging, and biomedicine.
We believe there are still many interesting abilities in gallium, which have not been discovered yet. Therefore, we will continue to explore new abilities of this material and transform them into critical functions for miniature robots.
3. Flexure Mechanisms
Flexure mechanisms are flexible structures that are designed to deliver desired motions via elastic deformations. Due to their unique actuation, these structures can effectively eliminate backlash and dry friction, allowing them to achieve highly repeatable motions. As a result, flexure mechanisms have become the ideal candidates for constructing high precision robotic systems, and they have been deployed across a wide range of applications pertaining to biomedical research, microscopy technologies and various industrial manufacturing processes.
From the design perspective, the performances of many existing flexure mechanisms are still not optimal. Hence, here we will explore new design methods that can successfully address such issues such that engineers can fully utilize such machines. |

| Dr Madhavan Nallani | We are interested in combining the proteins with polymeric self-assembled architectures. We aim to select the proteins either from nature or modified ones (e.g. by re-combinant ways or synthetic de-novo peptides). Block co-polymers as self-assembled architectures offer a unique possibility for the structural control of materials at the nano-scopic scale. Such control enables one to tune the properties for specific applications. We are exploring the above combination in applications such as sensing. |
| Asst Prof Marco Battiato | In the past, Marco Battiato developed the model of superdiffusive spin transport as a mechanism of the ultrafast demagnetisation, prediction which was experimentally confirmed. He has worked since then on several topics that stemmed from the discovery of the ultrafast spin transport: 1) ultrafast spin injection, 2) triggering of ultrafast demagnetisation via injection of excited unpolarised carriers, 3) ultrafast increase of the magnetisation, 4) generation of THz emission via injection of ultrashort spin current pulses in high SO coupling materials, and 5) injection of ultrashort spin current pulses from ferromagnetic metals into semiconductors.
He is currently interested in a wide range of phenomena that arise from the complex interplay of strongly out-of-equilibrium electronic populations in real band-structures, out-of-equilibrium transport in multilayers, and formation of THz electromagnetic fields. He is developing a massively parallel solver for the full Boltzmann-Maxwell system for real space transport in ab-initio band-structures, using the most general (without close to equilibrium approximations) expression of the collision operator for strongly out-of-equilibrium thermalisation dynamics.
He is applying the method to:
- Thermalisation of laser excited carriers in topological insulators;
- Ultrafast spin transport in metallic multilayers and metal-semiconductor junctions;
- THz emission after laser excitation of multilayers;
- Ultrafast dynamics triggered by THz excitation.
Finally one of his main goals is the construction of all the building blocks of ultrafast THz spintronics using the sub-picosecond spin current pulses as vector of information. |

| Assoc Prof Massimo Pica Ciamarra | We are interested in understanding the physics of disordered many-particle systems via statistical mechanics tools and numerical simulations, which is arguably one of the most pressing needs in material science. Such an understanding is crucial to 1) design atomic or polymeric disordered materials with specific mechanical and rheological properties; 2) rationalize natural catastrophic events, such as earthquakes and avalanches; 3) improve the many industrial products and processes handling particulate media, from the food to the pharmaceutical and the electronic industry. The main difficulty is the developing of a theoretical framework connecting the macroscopic and the microscopic scales in the presence of disorder. Some topics of specific interest are:
1. glass transition
2. suspensions of soft deformable particles, e.g. microgels
3. liquid with density anomalies
4. rheological properties of disordered particulate systems, with applications to earthquakes

| Asst Prof Ni Ran | The concept of "soft matter" was first introduced by Pierre-Gilles de Gennes in his Nobel lecture in 1991. Essentially, soft matter is a subfield of condensed matter comprising a variety of physical systems that are deformed or structurally altered by thermal or mechanical stress of the magnitude of thermal fluctuations. Because of their responsivity with respect to perturbations, e.g. thermal fluctuations, mechanical deformation, external fields, etc., soft matter have shown great promise as the next generation “smart materials”.
In our group, we use computer simulation as a tool to study and predict the structural properties and dynamic behaviour of soft matter systems in and out of equilibrium to direct the experimental fabrication of functional materials. In particular, we are interested in the self-assembly of colloidal and (bio) polymer systems and work synergically with experimentalists to design new functional materials with application in photonic devices, bio-sensor, bio-materials, etc. Presently, we are interested in the projects below:
1. Dynamic assembly of active matter
2. Glass transition of anisotropic colloids
3. Hierarchical self-assembly of anisotropic colloids
4. Self-assembly of fibril-forming polypeptides |

| Prof Peter Preiser | My research interests focus on the molecular mechanisms by which the malaria parasite is able to avoid host immunity and adapt to changes in the host cell environment. One of the main problems in developing an efficient malaria vaccine is the ability of the parasite to evade host immune responses. Immune evasion happens both at the level of the infected red blood cell and at the process of invasion, the step at which the parasite infects a new cell.
A key focus area of the lab is to understand the mechanisms on how the malaria merozoite recognizes and penetrates the erythrocyte. To address these questions we have particular focused on the role of the Reticulocyte Binding Protein Homologues (RH) family of proteins which is found in all malaria species and has been implicated on playing a role in immune evasion and parasite virulence. Using both the human parasite Plasmodium falciparum as well as the rodent parasite P. yoelii we have been able to address question relating to mechanisms regulating parasite virulence as well as getting a cleared understanding on how these large proteins mediate their function. An interesting upshot of this work is the possibility of using them as part of a malaria vaccine formulation.
In addition to merozoite invasion the lab has also spend significant effort in elucidating the biological role of the STEVOR and PIR multigene families identified in P. falciparum and P. vivax respectively. While STEVOR is unique to P. falciparum the PIR multigene family is found not only in P. vivax, but also rodent and simian malaria parasites. My research group has focused on developing a range of reagents that allow us to address what the role of STEVOR is in parasite development. We have recently been able to show that STEVOR is highly expressed in patient isolates and may play an additional role in immune evasion. We are now further characterizing how STEOVR functions. The PIR gene family provides a unique opportunity to study antigenic variation in a rodent model and possibly utilize the information gained in this system to understand how these genes may work in the intractable human parasite P. vivax. Currently, our efforts focus on understanding how the pir genes are transcriptionally regulated.
A more recent effort is to gain new insights into how human malaria parasites interact with their host. Until recently most research efforts have focused on using culture adapted parasites but it has become clear that significant information in relation to host parasite interactions are lost in this system. We are therefore interested in using the P. falciparum and P. vivax microarray platform developed here at NTU (in collaboration with Professor Zbynek Bozdech) to investigate differences in the transcriptional profile of parasites obtained directly from patients with different clinical symptoms. This effort has recently given significant new insights into the biology of P. vivax. |

Dr. Singh’s recent research focuses on addressing the issue of losses in subwavelength plasmonic metamaterials and investigates new dynamic materials that could be integrated with metamaterial resonators to achieve the active control of the photonic devices with exotic properties. |
| Asst Prof Rupshi Mitra | Neurobiology of Resilience
Stress targets everyone; but not everybody succumbs to it. Some develop stress-related psychopathology, anxiety, depression, dementia, while others weather it well and even emerge healthier. What makes some individuals resilient and others not? Comprehensive studies on 9/11 survivors and war veterans report that positive emotion helps resilient people re-route physiological resources activated by stress into successful coping strategies. Stress is known to cause brain damage, shrink neurons of hippocampus (memory center of brain) and enhance emotional learning along with neuronal growth in amygdala (emotion center of brain). Our research (@ Resilieo) is geared to find out how we can minimize and prevent brain damage caused by stress. Also, what is different and special in resilient individuals in terms of brain changes during/after stress? With this backdrop, we venture into 4 different lines of investigation.
1. Is there any difference in brains of resilient and vulnerable individuals?
Our study on rats exposed to predator stress showed distinctive pattern of neuronal branching within amygdala of resilient individuals. Well-adapted (resilient) animals had more densely packed neuronal branching and maladapted (vulnerable) animals had more spread out neuronal branching of amygdala neurons. Questions we are pursuing now include, what determines individual variation in neuronal branching? And what are the possible factors mediating this?
2. How to rescue or prevent stress-induced damages (enhance resilience)?
In addressing this question we employed gene therapy as a technique to deliver genetically altered proteins through viral vectors into specific brain regions. Targeted infusion of therapeutic molecules within amygdala rescued stressed animals from maladaptive anxiety, abnormal stress-response and neuronal over growth (hypertrophy). We continue to identify newer molecules for therapeutic intervention within amygdala and other brain regions.
3. Developing animal model of resilience
Enriched environment is known to induce positive behavior and protection against brain damage. We are testing different enrichment paradigms to develop a testable animal model of resilience. Initial results are promising. Short term enrichment rescues maladaptive fear response in stressed animals.
4. Are resilient individuals better adapted?
In an interesting new finding we showed that male rats exposed to enriched environment for a short 2 week period were more attractive and preferred as mates by females over non-enriched males. The enriched male rats also had stronger defense response against predator. Thus resilience not only makes individuals cope better with stress, but also has a bigger scope of adaptability in an ever-changing environment. Resilience triggers several physiological pathways that are directly beneficial for basic survival drives, namely, reproduction/mate-choice and protection from danger. We continue to investigate how enrichment drives basic physiology to be more adaptive? What are the pathways and molecular factors triggered by enrichment in this context?

| Asst Prof Terry W.J. Steele | Surface Functionalization of Thin Films
Surface functionalization of biocompatible materials is an area under tremendous development for medical implants. The medical implant bulk materials often lack the required surface properties needed for blood compatibility (hemocompatibility), tissue adherence, or promotion of host-cell growth. Secondary surface modifications attempt to address these issues with the grafting of known biocompatible polymers.
To address the significant need for a highly versatile surface coating, we have designed a surface function methodology that incorporates water based ‘green chemistry’, acrylate-based combinatorial libraries, and living polymerization techniques. This strategy will be applicable to most known materials typically employed for solid medical implants, while providing an unprecedented versatility with a wide choice of functional groups, surface densities, and layer thicknesses.
Ocular Delivery Through Periocular, Unidirectional, Biodegradable Discs
We propose an innovative practical and proactive strategy to circumvent the practical hurdles in delivering the anti-CMV drug to the retina, in a safe, effective and affordable manner. We propose to develop a unidirectional nano-drug delivery technique that remains periocular (subtenon’s space) but provides drug delivery into the vitreous over a prolonged or intermittent period yet maintain an adequate concentration at the retina. We will design a biodegradable disc with selective permeability on the two surfaces. The surface adjacent to the sclera will be permeable for unidirectional drug delivery into the eye, while the other surface will be non-permeable, thus obviating the risk of diffusion of the drug externally.
The aim of the therapy is to suppress viral replication, halt the progression of disease, minimize retinal damage, prevent drug resistance, prevent local complications and preserve visual function. In short term, the proposed biodegradable disc will aim to deliver the optimal concentration of the drug near site of lesion and the concentration of the drug will remain sustained over period of six months thereby preventing the need for repeated intraocular injections and also prohibit the patient to come to clinic for repeated injections. Removable after six months won’t be necessary as well, as the polymer components are designed to slowly dissolve and be metabolized into the tissue.
Blood Vessel Joining (Anastomosis) With Adhesive Biodegradable Inserts
Anastomosis—the joining of two blood vessels—requires precise placement of sutures through the two blood vessels that need to be healed together. The technique is technically challenging and requires a long learning curve through practice on cadavers, in vivo animal sacrifices, or both. The suturing practice of today has been nearly the same for 100 years.
As the surgical theatre continues toward laparoscopic and keyhole surgeries, catheter based methods for surgical anastomosis will be sorely needed. Practical limitations to vascular surgeon’s abilities limit sutures to only the most easily accessed vessels and vessel diameters greater than 1 mm. New methods are needed for impossible to access areas such a cerebral blood vessels (i.e. stroke treatments). Methods to join micro-vasculature—such as arterioles and venules—are needed to advance severed limbs and associated limb or organ transplants.
Pipe sleeves in construction and plumbing are commonly used to join gaps, protect pipes from the environment, and repair damaged or leaky plumbing. Similarly, we have designed biodegradable pipe sleaves made from FDA approved implantable polymers.
In our design, the polyesters would be cast into thin film cylinders, no longer than 1-2 cm, 0.5-5 mm in diameter, and 100-500 micrometers thin. These cylinders would incorporate pressure sensitive adhesives on their outer surface to seal and join two opposing blood vessels. |
