We report a novel process to selectively pattern nanomaterials, specifically gold nanoparticles, onto a silicon surface through click chemistry, to consistently and efficiently join together small units through a quick and simple reaction. We employed the UV-initiated thiol-ene reaction, which is used in tandem with microcontact printing. Dithiol-capped nanoparticles were used as a printing ink and were grafted onto ene-terminated Si(100) wafers by pressing a nanoparticle-impregnated poly(dimethylsiloxane) stamp, while irradiating with ultraviolet light to activate a radical initiator. The resulting structures were characterized using scanning electron microscopy and atomic force microscopy.
