首次证明了聚苯乙烯乳胶或二氧化钛颗粒在溶液中的激光扫描显微操作和空间图像化。一个捕获激光束被计算机控制的振镜以13大约50赫兹的频率重复扫描，使微米级粒子沿着扫描激光束产生的图案排列。讨论了本技术的特点。
Laser-scanning micromanipulation and spatial patterning of polystyrene latex or titanium dioxide particles in solution were demonstrated for the first time. A trapping laser beam was repetitionary scanned at 13 approximately 50 Hz by computer-controlled galvano mirrors to align micrometer-order particles along the pattern produced by the scanning laser beam. Characteristic features of the present technique are discussed.
