中文摘要	in this paper, the fabrication of an active surf ace-enhanced raman scattering (sers) substrate by self-assembled silver nanoparticles on a monolayer of 4-aminophenyl-group-modified glassy carbon (gc) is reported. silver nanoparticles are attached to the substrate through the electrostatic force between the negatively charged silver nanoparticles and the positively charged 4-aminophenyl groups on gc. the active sers substrate has been characterized by means of tapping-mode atomic force microscopy (afm), indicating that large quantities of silver nanoparticles are uniformly coated on the substrate. rhodamine 6g (r6g) and p-aminothiophenol (p-atp) are used as the probe molecules for sers, resulting in high sensitivity to the sers response, with the detection limit reaching as low as 10(-9) m. this approach is easily controlled and reproducible, and more importantly, can extend the range of usable substrates to carbon-based materials for sers with high sensitivity.
