Abstract

Abstract : A simple, specific, label-free and general nucleus imaging strategy was developed based on in situ fluorescence activation of silver nanoclusters. Abstract : A facile, general and turn-on nucleus imaging strategy was first developed based on in situ fluorescence activation of C-rich dark silver nanoclusters by G-rich telomeres. After a simple incubation without washing, nanoclusters could selectively stain the nucleus with intense red luminescence, which was confirmed using fixed/living cells and several cell lines.
