title: DNA-regulated silver nanoclusters for label-free ratiometric fluorescence detection of DNA.
abstract: Two kinds of DNA-regulated Ag nanoclusters were one-pot synthesized on an oligonucleotide, and delicately utilized in the design of a label-free ratiometric fluorescence strategy for DNA detection with simplicity and high sensitivity.
