Abstract: A fiber optic based particle manipulation system employs one or more optical fibers for emanating a refracted optical manipulation signal directed at a target particle for fixing or manipulating the particle for examination, research and manufacturing. A target particle may be a living cell or inanimate sample or compound of matter. An alignment linkage controls optical fibers carrying the manipulation signal for focusing one or more manipulation signals on the target particle. Manipulated particles occupy a fluid medium of either liquid or gas, and are responsive to the manipulation signal based on both photon bombardment and temperature differential from photon contact. The temperature differential is based on surface properties of the target particle, as smooth particles tend to exhibit a greater thermal differential for stronger displacement forces driving or affecting the target particle.
