title: Random dsDNA-templated formation of copper nanoparticles as novel fluorescence probes for label-free lead ions detection.
abstract: A simple label-free method for the detection of Pb(2+) ions with high selectivity and sensitivity has been developed by using random double-strand DNA-templated formation of copper nanoparticles as novel fluorescence probes in aqueous solution.
