Advanced Laser Processing Research Team
Our research team is developing advanced laser processing techniques which realize low environmental load, high quality, high efficiency fabrication of materials. In particular, by using femtosecond lasers, novel material processing techniques including 3D fabrication, surface nanostructuring, novel nanomaterial synthesis, and tailored beam processing are developed, which are applied for fabrication of functional micro/nanodevices. As one of examples of the 3D fabrication, our team successfully created a 3D complex shape of pure protein such as bovine serum albumin (BSA). Furthermore, enhanced green fluorescent protein and enhanced blue fluorescent protein were formed on a single substrate to realize a two-color fluorescence image exhibiting a RIKEN logo. The 3D proteinaceous micro and nanostructures fabricated by this technique will offer many applications including cell culture, tissue engineering, biochips, micromachines, etc.
