Nanoparticles have been strongly attracted in various fields due to their unique physicochemical properties. This study investigated a potential of microfluidic nanoparticle concentration using fluidic force induced by alternating-current electric field. We have developed three-dimensional measurement system for microfluidic velocity field and quantified detailed three-dimensional flow field of the electric-field-induced flow. An evaluation technique for three-dimensional concentration distribution of nanoparticles were established. Consequently, the localized concentration of metal and latex nanoparticles in a microchannel with alternating-current electric field was achieved.

纳米粒子以其独特的物理化学性质在各个领域受到了极大的关注。本研究利用交变电场诱导的流体力，研究了微流控纳米颗粒的浓缩潜力。研制了微流控三维速度场测量系统，对电场诱导流动的详细三维流场进行了定量化。建立了纳米颗粒三维浓度分布的评价技术。从而实现了金属和乳胶纳米粒子在交变电场作用下的微通道内的局部浓缩。
