title: A one-step homogeneous plasmonic circular dichroism detection of aqueous mercury ions using nucleic acid functionalized gold nanorods.
abstract: In this work, we report the application of gold nanorods ladder assemblies as chiroptical sensors for detecting mercury ions (Hg(2+)). By taking advantage of the Hg(2+)-mediated T-T base pair of DNA and the high sensitivity of CD measurements, the method offers a simple and sensitive detection of target Hg(2+) residues in water. Therefore, the developed method will be a promising tool for monitoring heavy metal ions, other small molecules and biomacromolecules.
