Evidence for Rigid Binding of Rhodamine 6G to Silica Surfaces in Aqueous Solution Based on Fluorescence Anisotropy Decay Analysis
Abstract
Strong ionic binding of the cationic probe rhodamine 6G (R6G) to the anionic surface of silica particles in water provides a convenient labeling procedure to study both particle growth kinetics and surface modification by time-resolved fluorescence anisotropy (TRFA). The decays for R6G dispersed in diluted Ludox silica sols usually fit to a sum of picosecond and nanosecond decay components, along with a significant residual anisotropy …
