Surface Assembly and Redox Dissolution of Silver Nanoparticles Monitored by Evanescent Wave Cavity Ring-Down Spectroscopy
The adsorption kinetics of Ag nanoparticles on a silica surface modified with poly-l-lysine (PLL) have been measured in situ by following the interfacial optical absorbance at 405 nm by evanescent wave cavity ring-down spectroscopy (EW-CRDS). Sensitivity toward nanoparticle detection is enhanced due...
