Silver nanoparticles have been used as anti-bacterial agent, as a substrate for surface plasmon resonance and surface-enhanced Raman scattering (SERS) measurement. So far, silver nanoparticles have been prepared through several methods; chemical reduction, microemulsion, sol-gel, electrolysis method and so on. We report on a very simple and convenient method for the preparation of unifom silver nanoparticles embedded on PEG-modified glass slides under mild condition without any chemical reducing agents. We could obtain uniform silver nanoparticles embedded on glass slides in size of about 50 nm. Silver nanoparticles on glass slides were anaylized by AFM, FE-SEM and XPS.
