Abstract In photodynamic therapy (PDT), light-sensitive photosensitizers produce reactive oxygen species (ROS) after irradiation in the presence of oxygen. Atomically-precise thiolate-protected gold nanoclusters are molecule-like nanostructures with discrete energy levels presenting long lifetimes, surface biofunctionality, and strong near-infrared excitation ideal for ROS generation in PDT.

Abstract The impact of single and multiple gold atom doping on optical properties of silver nanoclusters was analysed in linear and nonlinear regime experimentally and with TD-DFT simulations. Ag24Au1 nanocluster is a robust emitter, with strongly enhanced luminescence quantum yield and two-photon brightness with respect to Ag25 parent nanocluster. Abstract Noble metal nanoclusters allow for the atomically-precise control of their composition.
