Koji Sugioka plenary talk: Femtosecond Laser 3D Micromachining and its Applications to Biochip Fabrication

Presented at SPIE Photonics West 2014

4 March 2014, SPIE Newsroom. DOI: 10.1117/2.3201403.21

Koji Sugioka, RIKEN (Japan)In his plenary talk, "Femtosecond Laser 3D Micromachining and its Applications to Biochip Fabrication," SPIE Fellow Koji Sugioka of RIKEN (Japan) details the fabrication procedure of biochips using the femtosecond laser and applications of the fabricated biochips to material synthesis, analysis of biochemical samples, and determination of functions of miroorganisms.

Femtosecond lasers have opened up new avenues in materials processing due to their unique characteristics of ultrashort pulse widths and extremely high peak ntensities that induce strong absorption in even transparent materials due to nonlinear multiphoton absorption. Then, the femtosecond laser can directly fabricate three-dimensional microfluidic, micromechanic, microelectronic, and micro-optical components in glass. These microcomponents can be easily integrated in a single glass microchip, which enable the fabrication of functional biochips quickly screening large number of biologicalanalytes.

Sugioka received his BS, ME, and PhD degrees in engineering from Waseda University in 1984, 1986, and 1993, respectively. He is now a senior research scientist in RIKEN and a guest professor at Tokyo University of Science and Tokyo Denki University. He is currently a member of the board of directors for Laser Institute of America and Japan Laser Processing Society.
