A peptide was designed to generate a sub-nanometric template that guides the growth of fluorescent gold nanoclusters. The peptide was endorsed with nucleating moieties and a three-dimensional structure that arrests the growth of ultrasmall nanoparticles. The nanoclusters are not cytotoxic and can be found in the cytosol of cells.
