The principal purpose of the laboratory is to explore a new frontier of research field which fuses engineering and biological science. On the basis of polymer chemistry, analytical chemistry, surface chemistry, biochemistry and molecular biology, we are studying on new materials comprising biological components, novel methodology for bioanalysis and medical diagnosis, and artificial systems for regulation of biological processes. Those new ideas and materials are being applied to the field of biomaterials science, environmental science, micro/nanoscience, life science and medical engineering. For example, we newly prepared DNA-vinyl polymer conjugates which have been applied for DNA biosensor, affinity electrophoresis, SNPs-responsive diagnostic nanoparticle, gene-responsive hydrogel, artificial gene regulation system, etc. These researches may be classified into a new category, i.e., "DNA engineering".
