Abstract

A biosensor based on Hg(II) nanoladders integrated with graphene oxide (GO) for Hg(II) detection was developed. Nanoladders were essentially DNA sandwich structures supported by T–Hg(II)–T and were used for Hg(II) trapping and signal translation. GO was used to differentiate the fluorescence generated by Hg(II) nanoladders from a background signal.
