| Popis: | 104 In this work, a facile electrochemical procedure has been proposed for the fabrication of melamine-functionalized gold nanoparticles on ITO electrode as SERS substrates for detection of bisphenol A. First, seed-mediated growth was used to deposit gold nanoparticles. With the growth of the nanoparticles, the gap between the adjacent nanoparticles gradually decreases, and thus plenty of “hot spots” are formed on the substrate for SERS applications. Second, melamine functionalization on SERS substrates was based on diazotization, which is an electro-initiate process.The procedure for melamine-functionalized SERS substrates was cheap, rapid, and eco-friendly with full control by electrochemical procedure. The substrate was used to detect bisphenol A, a typical endocrine disruptor in the environment to show its sensitivity and stability. |
