Abstract

Microparticle manipulation: The photoisomerization of surfactants adsorbed at a gas-liquid interface drives a Marangoni flow that can be used for the trapping and manipulation of small particles. By switching the laser wavelength, a flow either into or away from the focal spot can be induced. The picture shows a microparticle trapped in the focal region by the inflow.
