摘要：
Gold nanoparticles (Au NPs) were synthesized by reduction of hydrogen tetrachloroaurate and used as a facile and highly selective sensor for the visual detection of hexaconazole. The presence of hexaconazole could rapidly induce the aggregation of gold nanoparticles, thereby resulting in red-to-blue (or purple) colour change. The concentration of hexaconazole was determined by the naked eye visually and could further be monitored by an UV-VIS spectrometer with a limit of detection (LOD) about 0.7 × 10-6 mg/L. The highest selectivity was proved...
