摘要：

A silver mirror reaction method was applied to deposit silver nanoparticles on a glass substrate. The effect of different reagents on these silver mirror substrates was investigated. SEM image for this silver mirror substrate shows that the average diameter of silver nanoparticles is about 200 nm. The surface-enhanced raman scattering( SERS) spectra of 4-aminothiophenol(PATP) molecule on this substrate were measured. The results indicated that the SERS-active silver mirror substrate made in this way has an enhancement factor of 4.6 x 10(5). These substrates were used to collect the surface-enhanced Raman spectra of furazolidone, which were widely used deleterious antibiotics. It was found that furazolidone might interact with silver surface through the lone pair electrons of the C=N nitrogen atoms.
