Remotely powered floating microswimmers as colloidal microparticle manipulators.

Abstract : Remote propulsion of micro scale mobile agents has great potential as wireless manipulation tools for smaller scale objects. These untethered micro mobile agents can enlarge the area of manipulation that can open broad applications. Especially in harsh and inaccessible environments like toxic liquids, these untethered devices are important because they enable some applications which were impossible before. Liquid environment manipulation using untethered mobile agents can be used as new manipulation methods in biologic and in interest of such novel manipulation tools. However low Reynolds number physics severely limits the propulsion performances of such small scale mobile agents. To overcome such physical limitation, biologically inspired artificial flagella [1] have been demonstrated to swim efficiently in liquid environments with magnetic fields. The swimming performance of electro-osmotic propulsion could be also even more efficient [2]. However most of such micro scale mobile agents liquid applications are limited to the immersed environment. If macro scale, the floating diode propulsions were demonstrated by electro-osmotic force [3]. However floating micro scale mobile agents were not much studied in their propulsions and manipulation. In this paper, the propulsion of floating microswimmers is proposed to demonstrate the cargo transport of colloidal micro particles. Since these floating mobile microswimmers can trap and release the massive amounts of colloidal particles in parallel, they can be applied to long distance wireless liquid manipulation tools.
