Nanoscopic Functional Chemistry

assembly / disassembly / arrangement -> construction / utilization / understanding


The nanoscopic fields exhibit strange features owing to heterophase intersections and molecular competitions. For instance, molecular behaviors at nano-interfaces/spaces are much different from those in the bulk phase. In the context of these knowledges, our research focuses on the development of precise and adjustable manipulation strategies of nanoscopic fields and their functions by materials engineering-based approaches. Furthermore, we keep trying the application of these nanoscopic functions to analytical chemistry and organic electronics. 

On-demand preparation of molecular recognition fields

To modulate the analyte selectivity of molecular sensors simply, we develop new materials and processes for controlling the organization of molecular recognition components in nanoscopic fields. In addition, we are tackling the integration and parallelization of versatile sensing fields onto a 1 chip for quantitative and comprehensive visualization of molecular dynamics anytime, anywhere.  [ex.: ACS Appl.

In general, "the presence of water" is a contraindication in the operation of semiconductor devices. Whereas, high-level carrier dopants can be formed by utilizing some kind of aqueous media containing electrolytes under an extremely low electric field at nanointerfaces. By focusing on such features of the system, we carry out the preparation of 'aquatic' semiconductor devices for achieving eco-friendly electrical devices and high-performance chemical sensors.
