  • Title: A graphene platform for sensing biomolecules.
    Author: Lu CH, Yang HH, Zhu CL, Chen X, Chen GN.
    Journal: Angew Chem Int Ed Engl; 2009; 48(26):4785-7. PubMed ID: 19475600.
    Abstract:
    Sensitive platform: The use of graphene oxide (GO) as a platform for the sensitive and selective detection of DNA and proteins is presented. The interaction of GO and dye-labeled single-stranded DNA leads to quenching of the dye fluorescence. Conversely, the presence of a target DNA or protein leads to the binding of the dye-labeled DNA and target, releasing the DNA from GO, thereby restoring the dye fluorescence (see picture).
