Understanding the Evolution of Luminescent Gold Quantum Clusters in Protein Templates

We show that the time-dependent biomineralization of Au3+ by native lactoferrin (NLf) and bovine serum albumin (BSA) resulting in near-infrared (NIR) luminescent gold quantum clusters (QCs) occurs through a protein-bound Au1+ intermediate and subsequent emergence of free protein. The evolution was p...
