摘要：

We study the formation and the propulsion properties of chains of dielectric microspheres in the evanescent field of a channel waveguide made by Cs+ ion-exchange. Particle chains are shown to move faster than single particles. We exploit counter-propagating waves for axial positioning of single and chains of microspheres. The particles can be propelled back and forth at will, and trapped at a given point for several minutes. We demonstrate that this technique can also be used to assemble a long, one-particle wide, chain. (C) 2007 Optical Society of America
