  • Title: Nitrogen-doped, thiol-functionalized carbon dots for ultrasensitive Hg(II) detection.
    Author: Gupta A, Chaudhary A, Mehta P, Dwivedi C, Khan S, Verma NC, Nandi CK.
    Journal: Chem Commun (Camb); 2015 Jul 07; 51(53):10750-3. PubMed ID: 26051389.
    Abstract:
    Nitrogen-doped, PEGylated carbon dots (C-dots) have been synthesized for the detection of mercury ions (Hg(2+)). 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-Hg(2+) system was also able to efficiently detect biothiols.
