Control of photofunctionality and chemical reaction of single organic microparticles by optical manipulation

从1998年4月到2002年3月，我们对单个有机纳米粒子进行了系统的小组研究。每位成员的标题如下，Hiroshi MASUHARA单个有机纳米粒子的操纵。Kikuo CHO。光与单粒子相互作用的理论研究。颗粒间相互作用和反应的控制hachiro NAKANISHI尺寸控制有机和聚合物纳米晶体的制备和表征HORIE skazuyuki单聚合物颗粒的光反应和传感。单液滴大小依赖性反应。微粒子和纳米颗粒作为胶体科学和表面科学的重要材料受到广泛关注，被认为是新概念和新技术的宝库。为了扩展新的微粒子和纳米粒子的研究，我们致力于阐明纳米粒子的物理和化学性质，作为它们的大小、形态和内部结构的函数。通过这种非常规的方法，开发了各种控制纳米颗粒纳米取向、fN相互作用和μs/nm分子扩散的方法，并展示了在功能材料和化学反应中的新应用。所有的结果将被总结成一本报告书，并将广泛分发。

We have conducted systematically a group research on single organic nanometer particles for 1998 April - 2002 March. The title of each member is as follows,Hiroshi MASUHARA Manipulation of single organic nanometer particles.Kikuo CHO Theoretical study on interaction between light and single particle.Tadashi ITOH Control of interparticle interactions and reactionHachiro NAKANISHI Preparation and characterization of size-controlled organic and polymer nanocrystalsKazuyuki HORIE Photoreaction and sensing of single polymer particles.Notoru KITAMURA Size-dependent reaction of single droplets.Micro- and nanoparticles have received much attention as important materials for colloid and surface science, and are considered to be a treasure house for new concept and new technology. To extend new micro- and nanoparticles studies, we have devoted to clarify physical and chemical properties of nanometer particles as a function of their size, morphology, and inner structure. By the present unconventional approaches, various control methods for nanometer orientation of nanoparticles, their fN interactions, and μs/nm molecular diffusion are developed, and new applications to functional materials and chemical reaction are demonstrated. All the results are summarized as a report book and will be distributed widely.
