A simple and sensitive sensor for rapid detection of sulfide anions using DNA-templated copper nanoparticles as fluorescent probes

A simple and rapid method for the detection of S(2-) anions 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.
