Luminescent silver nanoclusters anchored by oligonucleotides detect human telomerase ribonucleic acid template

Luminescent silver nanoclusters were anchored by designed oligonucleotides. After hybridizing with human telomerase RNA template, the luminescence of the cluster decreased linearly with respect to the concentration of the complementary strand (25–250 nM). The cluster is therefore a potential candidate for human telomerase detection.
