Enhanced fluorescence of silver nanoclusters stabilized with branched oligonucleotides. 
DNA stabilized silver nanoclusters (AgNCs) are promising optical materials, whose fluorescence properties can be tuned by the selection of the DNA sequence employed.  In this work we have used modified oligonucleotides in the preparation of AgNCs.  The fluorescent intensity obtained was 60 times higher than that achieved with standard oligonucleotides.
