摘要：

(Graph Presented) 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 NIH3T3 cells. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
