Function of Graphene Oxide as the “Nanoquencher” for Hg<sup>2+</sup> Detection Using an Exonuclease I-Assisted Biosensor
Graphene oxide is well known for its excellent fluorescence quenching ability. In this study, positively charged graphene oxide (pGO25000) was developed as a fluorescence quencher that is water-soluble and synthesized by grafting polyetherimide onto graphene oxide nanosheets by a carbodiimide reacti...
