Abstract

We demonstrate enhancement of fluorescent signals in close proximity to silver nanoparticles manufactured by the modified silver mirror reaction. The manufacturing process is bottom-up, non-vacuum, and completed in only 15 minutes, and thus, is differentiated from other deposition processes of metal nanoparticles. We have extended the process to manufacture submicron silver nano-islands composed of nanoparticles using micro-contact-printing of SAM. The fluorescent signals of rhodamin- 6G was enhanced by a factor of 5 on the silver nano-islands substrate.
