Abstract

Microparticles such as colloids and microorganisms moving in viscous liquid interact with each other via hydrodynamic interaction and often exhibit complex collective behaviors. In this study, we observed the collective motion of many colloids moving along the same circular path in water by utilizing optical vortex. The characteristic collective motion including clustering and dissociation of the particles was observed and their dynamic patterns depend on the number of the particles on the path. By addition of different sized particles, the specific clusters can be selectively induced. Those experimental findings are reproduced by numerical simulation which takes into account the hydrodynamic interaction with Oseen approximation and the radial optical trapping force.
