By combining mature microfabrication technology with biomaterials and organic materials, we aim to develop a variety of nanoscale and molecular-scale devices that enable higher-order information processing. For example, medical bioelectronics, where semiconductor microfabrication technology is used for medical applications such as drug screening; organic electronics, where sensors are developed based on organic materials; and bioelectronics, where neural circuits are created using living cells to try to understand how the brain works.
