Bimetallic alloying gold-silver nanoclusters (Au-AgNCs) have been synthesized by a one-pot biomineralization synthesis route at vital molar ratio of Au/Ag precursors in the protein matrix. Unexpectedly, prepared Au-AgNCs could exhibit dramatically enhanced red fluorescence, which is about 6.5-fold and 4.7-fold higher than that common AuNCs core-shell Au@AgNCs, respectively. A rapid, selective, ultrasensitive fluorimetric method has thereby developed using as fluorescent probes toward...
