Outline
Research in our unit targets on the development of a multidisciplinary program involving the triad of chemistry, electronic materials, and biomedical/biological investigations based on molecular and nano-assembled building blocks of organic conductive materials. These materials introduce electrical characteristics to build up the complexity necessary for further understanding of the targeted biological/biomedical issues. They also enlarge the dimensions of synthetic organic chemistry and polymer chemistry. Eventually our research effort would be engaged toward new areas in biomaterials science and engineering through the angle of synthetic organic chemistry.
Recent Research Topic
Organic conductive biomaterials and biointerfaces
Our unit has utilized conducting polymers as a template to construct organic conductive materials. Although many applications of conductive polymers have been demonstrated feasible, there has been only limited research toward biological and biomedical applications based on the non-functionalized forms of conducting polymers. We have synthesized various molecular building blocks based on polyethylenedioxythiophene (PEDOT), one of the most stable conducting polymers. A variety of nanostructures have also been assembled. In the preliminary experiments, these materials have shown promising biocompatibility and electrical properties.
