摘要

A new method for fixing single polymer nanoparticles onto a substrate was developed by local photopolymerization. A nanoparticle, dispersed in ethylene glycol containing monomer, crosslinker, and radical photoinitiator, was moved to the surface of a glass substrate using a focused near-infrared laser beam. Local photopolymerization around the nanoparticle was induced by additional irradiation of an ultraviolet pulsed laser beam, resulting in the generation of an acrylamide gel containing the nanoparticle on the substrate. The nanoparticles become fixed and remained after washing. The morphology of the formed polymerized gel was evaluated by atomic force microscope (AFM) observation.
