Abstract

A novel optical technique for stirring or mixing microscopic objects in a microchannel flow was developed by utilizing laser radiation pressure. The author's group proposed a new technique to manipulate the particles clusters by installing cylindrical lenses in a light pass and by moving mirrors. The laser radiation pressure was distributed elliptically in the solution, thus the number of manipulated particles was increased. The cylindrical lenses were rotated by controlling motors, therefore the elliptic areas of laser radiation pressure were rotated like as a windmill. This study focuses on investigations of performance of “micro optical stirrer”.
