Nitrogen-doped, thiol-functionalized carbon dots for ultrasensitive Hg(II) detection

Author affiliations

Abstract

Nitrogen-doped, PEGylated carbon dots (C-dots) have been synthesized for the detection of mercury ions (Hg2+). The detection limit was found to be 6.8 nM. However, upon functionalization with dithiothreitol (DTT), it reached to as low as 18 pM. The C-dots–Hg2+ system was also able to efficiently detect biothiols.
