MEMS(Micro Electro Mechanical Systems) which is a technology realizing chemical analysis system and medical device with small and high quality, was achieved by microfabrication of silicon and polymeric material. Since material characteristics in nano-micro space is important in this fabrication process, computer simulation of meterials and fabrication process focusing molecular scale are studied. In addition, a new fabrication process using nanomaterials is researched in our laboratory.
In the experimental research, we fabricate a microfluidic device using micromachinig technique, and we develop a synthesis of nanomaterials such as metallic nanoparticles using the fabricated device. In addition, application of the synthesized nanomaterials to immune tests and catalysts for automobile exhaust gas.
In the research of simulation, the prediction of properties of polymer resist and rubber material, and simulation of laser processing and micropowder blasting are researched using parallel computing such as a supercomputer according to the calculation scale. Moreover, development of a novel fabrication process and materials using the simulation results about technical information and optical property of materials are carried out. We focus the characteristics of MEMS materials such as polymer resist in meso scale, and an application of developed materials to microsystem is pursued.
A new paper, entitled "Analyzing the Critical Mixing Time for the Liquid-Phase Reduction Synthesis of Monodisperse Gold Nanoparticles using Glass Microfluidics", has been accepted for publication to Microfluidics and Nanofluidics (Springer)(Dec. 27, 2021).
