Abstract

A self-assembled nanostar dimer based on the Hg2+-mediated T–T base pair of ssDNA has been developed as a SERS sensor for Hg2+ detection. The enormous enhancement of the electromagnetic field by the dimer structures facilitates extraordinary SERS intensity. The LOD is 0.8 pg mL−1 and its linear range is 0.002 to 1 ng mL−1.
