Study on the properties of gold nanoparticles as plasmonic sensing material for chlorothalonil detection
… detection. In this study, a simple technique of seed-mediated growth method (SMGM) has been successfully performed to grow gold nanoparticles (GNPs) onto solid substrates. The process parameters; seeding time, growth time and effect of capping agent’s molecular weight were investigated to monitor …
