Outline of Final Research Achievements

Various micro/nano surface-modification techniques such as photolithography, dip-pen lithography and micro-fluidic systems have been developed. And they were used to extend the functionalities of solid surfaces. While those approaches work in the “open space”, push&/pull systems which work in solutions have recently drawn considerable attention. While microscale, region-selective chemical reactions have remained unattainable. This work reports a micro-chemical pen that enables region-selective chemical reactions for the micro/nano surface modification. The chemical pen is based on the principle of microfluidic laminar flows. The micro scale diffusion layer performs as the working region of the surface modification. This work is the first demonstration of an open micro reactor. The characteristics of the micro chemical pen are confirmed by different types of reactions, including inorganic chemistry, polymer science, electrochemistry and biological sample treatment.
