在溶液中的聚合物乳胶粒子的三维激光操纵进行了演示。通过在光学显微镜下分别扫描聚焦激光束（1064 nm），将直径为几微米的聚合物胶乳颗粒空间排列成任意图案（字母和几何图形）。纳秒或皮秒355-nm激光脉冲对单个激光捕获的聚合物颗粒的照射是含有可聚合乙烯基单体和光引发剂的样品溶液，其导致颗粒在三维结构中的永久固定
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 respectively 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 is a sample solution containing polymerizable vinyl monomers and a photoinitiator brought about permanent fixation of the particles in three-dimensional structures
