Prof Bo Gunnar LiedbergThe 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. Selected publications 1.

Prof Boey Yin Chiang, FreddyBiodegradable Drug Eluting Stents (15 members): The group, co-led with A/P Subbu Venkatraman, has developed a platform drug eluting stent technology which is applicable for urological, coronary, vascular and cranial therapy. The patent is premised on a multi-layered fully biodegradable stent which can release multi-drugs simultaneously in a controlled release. A start up company, Acacia Biomedical, has been funded to $2m to commercialize the work. Ongoing work seeks to develop nano features on the stent surfaces to promote hemo-compatibility by endothelial cell growth. Electroactive Materials (12 members): The group, co-led with A/P Ma Jan, has developed a PZT blood pump and a frictionless micro-pump using PZT actuators for implanted drug release. The group is presently studying the development of a fully flexible polymer-based impedance pump. The group has formed a start up company to exploit this technology commercially. The group has also initiated computational modeling to seek optimal material designs. Synthesis of Rare Earth Nano-materials (8 members): This project seeks to use a pre-cursor and high energy approach to evolve desired nanosized morphologies for Rare Earth materials, including Yittrium, Cerium, Lanthanum etc. The processes employed include flame hydrolysis, electro-atomization, plasma spraying and atomization etc. Multi-functional bio-imaging probes for targeted cancer therapy (5 members): This project involves the development of biocompatible multi-functional nano-probes, for bio-imaging and targeted cancer therapy. It is a joint-collaboration with the prestigious Mayo Clinic, USA. The group, co-led with A/P Ma Jan and Dr Joachim Loo, has developed the capability of functionalizing these nanoparticles. Results from animal trials have shown these bio-imaging probes to be promising for targeted cancer therapy. The group is currently surface modifying these nano-probes to further increase their tumour-targeting efficiency.
