Abstract

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.

Schematic representation of the driving force. (a) The radiation force exerted on a fixed particle as a function of the relative position of a focused beam, (b) the radiation force exerted on a moving particle. The laser beam is scanned from left to right. Positive radiation forces are in the direction of the laser scan, and negative forces are opposite the scan direction.
