Ion-Concentration-Dependent Dynamic Mechanism of Thiolactic-Acid-Capped Gold Nanoclusters Revealed by Fluorescence Spectra and Two-Dimensional Correlation Spectroscopy

Background and Research Questions Atomic gold nanoclusters (AuNCs), with particle sizes typically not exceeding 2 nanometers, have garnered extensive attention in recent years due to their unique photophysical properties, making them highly advantageous in biomedicine, catalysis, and sensing. These properties include excellent catalytic activity, t...
