Abstract

Radiation pressure from a tightly focused laser beam can be used as optical tweezers to confine, position, and transport microparticles. This technique is widely applied in studies on biological cells, DNA molecules, and microchemistry with microdroplets and beads. We intend to apply an optical trapping technique to drive micromachines. The micromachines are produced by two-photon microstereolithography with photocurable resin. Optically-driven microturbine and nanotweezers have been already developed. Such optically-driven micro/nano machines can be widely used in new tools in bio-nanotechnology and biochip technology.
