In Laser Bio/Nano Science Laboratory, two topics of “Laser Trapping Crystallization” and “Laser Tsunami Crystallization” are conducted by utilizing lasers and microscopes. The former is realized by focusing intense near infrared CW laser into solution at room temperature. Molecular clusters, polymers, and small nanoparticles with size of a few nm can be trapped in solution and eventually nucleation is triggered. On the other hand, multi-photon excitation of solution induces its ablation leading to shockwave generation and cavitation bubbling which are followed by convection flow. This is used as spatially and temporarily controllable perturbation to induce crystallization in solution, and we named this phenomenon “Laser Tsunami Crystallization”. We have started to elucidate underlying molecular dynamics and mechanism of these two new crystallization behaviors, on which we will explore novel laser-induced phenomena in bio/nano research fields and develop new methodologies.
International collaborations not only for efficient advancement of our research but also for stimulating each other are under going. Especially, we have a strong relationship with "Hamano Junichi Laser Bio-Nano Science laboratory in Nara institute of science and technology". Both Prof. Hosokawa and Prof. Sugiyama in that lab are already known as pioneers in the field of laser induced molecular crystallization, and they have recently specialized into applications. We believe that our relationship will result in fruitful results, which can make a major impact on scientific fields. Futhremore, knowledge interchange and sharing novel materials with other collaborators are also engaged actively.

From a viewpoint of the education and the cultivation of young researchers, we sincerely would like to share our research program with young Taiwanese students. We believe that research life with foreign researcher during undergraduate/graduate period make broadens their outlook up to world wide-level and will significantly improve their language skill which is indispensable for the researcher. Thus our aim in education is to cultivate world-class scientists. We can enterprisingly help their growth through sending to overseas educations for several monthes and/or international conferences.
