提出了一种新的微操作技术，用于在微米尺度的空间图案上排列精细颗粒，并使颗粒沿所形成的图案连续沿着移动。 该技术基于聚焦的捕获激光束的重复扫描。 粒子流的速度可以通过扫描速度和激光功率来控制。 驱动力的起源被认为是理论和实验。
A novel micromanipulation technique is proposed for aligning fine particles on micrometer-scale spatial patterns and for moving the particles continuously along the formed patterns. This technique is based on the repetitive scanning of a focused trapping laser beam. The velocity of the particle flow can be controlled by scan speed and laser power. The origin of the driving force is considered theoretically and experimentally.
