Unravelling the aptamer-analyte interaction dynamics through fluorescence quenching in graphene quantum dots (GQDS) based homogeneous assays
Graphene quantum dots (GQDs) are used here as a biosensing platform for the recognition of the major food contaminant ochratoxin A (OTA), with a fluorescently labelled DNA aptamer (FAM OTA aptamer) functioning as the biorecognition element. The detection principle lies in the formation of noncovalen...
