dc.description.abstract | Flower-like gold nanoparticles, so called gold nanoflowers (AuNFs), were synthesized through the reduction of HAuCl4 with ascorbic acid in the presence of chitosan polymers. Chitosan-mediated AuNFs exhibited the distinct SERS signals of 2-chlorothiophenol (CTP) due to the presence of many interstitial gaps (so called hot spots) on the surface. For the facile silica coating, the AuNFs were conjugated with terminal carboxylate groups of (3-glycidyloxypropyl) trimethoxysilane (GPTMS), consequently forming alkoxy-terminated AuNFs which could facilely participate in the sol-gel reaction for silica coating. The resulting core-shell particles, i.e., CTP-adsorbed AuNFs with silica coating, exhibited the distinct SERS signals of CTP embedded within silica layer, warranting the effectiveness of this chemical strategy for spectroscopic labeling of Raman probes. | - |
