A method based on plasmon resonance Rayleigh scattering (PRRS) spectroscopy and dark-field microscopy (DFM) was established for the real-time monitoring of a click reaction at the single-nanoparticle level. Click reactions on the surface of single gold nanoparticles (GNPs) result in interparticle coupling, which leads to a red-shift of the λmax (Δλmax =43 nm) in the PRRS spectra and a color change of the single gold nanoparticles in DFM (from green to orange).
建立了一种基于等离子体共振瑞利散射（PRRS）光谱和暗场显微镜（DFM）的方法，用于在单纳米颗粒水平上实时监测点击反应。在单个金纳米颗粒（GNPs）表面进行的点击反应导致颗粒间耦合，这导致 PRRS 光谱中 λmax 的红移（Δλmax=43nm）和 DFM 中单金纳米颗粒颜色的变化（从绿色变为橙色）。
