Abstract

Based on the localized surface plasmon resonance (LSPR) technology, a novel plasmonic nanosensor with high sensitivity and high selectivity was prepared for the detection of trace sulfide ions on an individual Au@Ag nanoparticle. Furthermore, it could be used to monitor the sulfurization on an individual Au@Ag nanoparticle surface observed under dark-field microscopy (DFM).

摘要

基于局域表面等离子体共振（LSPR）技术，制备了一种具有高灵敏度和高选择性的新型等离子体纳米传感器，用于在单个Au@Ag纳米颗粒上检测痕量硫化物离子。此外，它还可用于监测在暗场显微镜（DFM）下观察到的单个Au@Ag纳米颗粒表面的硫化过程。
