Visual Detection of Hg(2+) in Aqueous Solution Using Gold Nanoparticles and Thymine-Rich Hairpin DNA Probes

We report a sensitive method for visual detection of mercury ions (II) (Hg(2+)) in aqueous solution by using gold nanoparticles (Au-NPs) and thymine (T)-rich Hairpin DNA probes. The thiolated Hairpin DNA probe was immobilized on the Au-NP surface through a self-assembling method. Another thymine-ric...
