Abstract
A very efficient protocol for synthesizing highly fluorescent,
protein-templated silver nanoclusters (Ag/NCs) has been discussed.
Two types of Ag/NCs (Ag<sub>9</sub>/HSA and Ag<sub>14</sub>/HSA),
although showing significant differences in their photophysical properties,
can be interconverted at will, which makes this study unique. The
Ag/HSA NCs have been quantified by several spectroscopic techniques,
and they find tremendous applications as photoluminescent markers.
Besides their rather easy synthetic methodology, our Ag/HSA NCs show
two-photon excitation properties that enable them to be used in bioimaging
