In Vitro and Intracellular Production of Peptide‐Encapsulated Fluorescent Silver Nanoclusters

Abstract

Every nucleolus has a silver lining: Formation of silver nanoclusters by fluorescence photoactivation was used for the staining of cells at low silver nitrate concentrations and ambient temperature. The picture shows picosecond lifetime images of peptide-encapsulated silver nanoclusters within NIH 3T3 cells.
