Abstract:
Novel luminescent silver nanoclusters (AgNCs) were synthesized utilizing DNA as templates by a simple, rapid and one-pot procedure. Luminescence studies indicated that these DNA-AgNCs exhibited strong emission with peak maximum at 624 nm. The fluorescence of the DNA-AgNCs was found to be quenched by Cu(2+) enabling its detection with high sensitivity and selectivity.
