Chemistry and analysis in integrated chemistry lab on chip

Abstract

It is indispensable for the realization of integration of chemical systems on a small substrate to characterize and control molecular behavior in a liquid microspace from a chemical viewpoint as well as the development of microfabrication techniques. We have characterized a liquid microspace in a microchannel by large specific interface area, short molecular diffusion distance, small heat capacity and localized uniform field. Molecular transport, reaction control, and other chemical operations were realized in a microspace by using these characteristics and photothermal techniques.
