(Received February 22, 1991; accepted for publication March 29, 1991)

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∼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.
