摘要：

Three-dimensional laser manipulation of polymer latex particles in solution was demonstrated. Polymer latex particles with a diameter of several microns were spatially aligned in arbitrary patterns (letters and geometrical figures) by repetitively scanning a focused laser beam (1064 nm) under an optical microscope. Irradiation of nanosecond or picosecond 355-nm laser pulses on individual laser-trapped polymer particles in a sample solution containing polymerizable vinyl monomers and a photoinitiator brought about permanent fixation of the particles in three-dimensional structures. Possible roles of the laser trapping/manipulation techniques in studying the chemistry and physics of polymeric microparticles are also discussed.
