INTRODUCTION. As promising substitutes to organic dyes and quantum dots, few-atom fluorescent noble metal nanoclusters of <2 nm in diameter have attracted a great deal of attention in recent years because of their potential applications in nanotechnology and nanomedicine ().In particular, much effort has been dedicated to the synthesis of fluorescent silver nanoclusters The photophysical parameters of the sulfonamide derivatives were Keywords: Substituent effect; absorption; fluorescence; photo-physical parameters.

In this paper, silver nanoclusters (AgNCs) were synthesized one facile, low-cost and green method with histidine acting as the stabilizer and ascorbic acid performing as reducing agent. AgNCs displayed excellent fluorescence property and good biocompatibility and were further functionalized -cyclodextrin (CD-AgNCs) for the highly Chameleon silver nanoclusters (AgNCs) have attracted substantial attention over traditional AgNCs, which provide new possibilities for the construction of ratiometric fluorescent biosensors. Herein, a novel method for sensitive and selective detection of miRNA is developed coupling chameleon AgNCs with hybridization chain reaction.

Providing the "missing link" between atomic and nanoparticle behavior in noble metals, these highly fluorescent, water-soluble gold and silver nanoclusters offer complementary transition energy size scalings at smaller dimensions than do semiconductor quantum dots. Fluorescent noble metal nanoclusters (gold or silver, for example) might be better tags than those currently available because fluorescent noble metal nanoclusters can exhibit a strong, size-dependent light emission, can be very small, and can be attached to biomolecules.
