Green synthesis and electrophoretic deposition of Ag nanoparticles on SiO2/Si(100) [link]Paper  doi  abstract   bibtex   
Plasmonic substrates were prepared by electrophoretic deposition of Ag nanoparticles on SiO2/Si(100). The Ag nanoparticles were obtained using [Ag(NH3)2]+ as the Ag precursor and d-glucose as the reducing agent. Under optimized conditions, this simple and green synthesis method furnished a suspension of Ag nanoparticles with a narrow dimensional dispersion (centered around 27 nm) and a negative z-potential, suitable for electrophoretic deposition. Samples were chemically, optically and morphologically characterized by photoemission and UV–vis spectroscopy and electron microscopy, and tested as substrates for surface enhanced Raman spectroscopy. Despite being a very simple procedure, good enhancement factors were measured thanks to the formation of hot spots, formed by sandwiching the analyte (benzenethiol) between sequentially deposited Ag nanoparticles.
