将光聚合与激光操作技术相结合，开发了一种将图案化纳米颗粒固定到基底上的方法。将纳米颗粒分散在含有单体、交联剂和光引发剂的乙二醇中，并聚集在玻璃基底上的捕获激光束（1064 nm）的焦点处。通过脉冲激光束（355 nm）的额外照射诱导纳米颗粒组装体内部和周围的局部光聚合，从而产生含聚丙烯酰胺的纳米颗粒。通过原子力显微镜观察评价聚合组装体。通过扫描捕获和激发激光束，图案化的纳米颗粒也可以固定在玻璃基板上。(C)2001年美国物理学会。
A method for fixing patterned nanoparticles onto a substrate was developed by combining photopolymerization with a laser manipulation technique. Nanoparticles were dispersed in ethylene glycol containing monomer, crosslinker, and photoinitiator, and gathered at the focal point of a trapping laser beam (1064 nm) just on a glass substrate. Local photopolymerization within and around the nanoparticles assembly was induced by additional irradiation of a pulsed-laser beam (355 nm), resulting in generation of polyacrylamide containing nanoparticles. The polymerized assembly was evaluated by atomic force microscope observation. By scanning both trapping and excitation laser beams, patterned nanoparticles could also be fixed on a glass substrate.
