Aflatoxin B1 (AFB1) exhibits high toxicity and has the potential to induce cancer, deformities, mutations. It is therefore highly desirable that sensitive straightforward methods for detecting AFB1 be developed. In this study, due specific adsorption capacity of aptamers, we applied a sensing strategy based on quantum dots (QDs) carboxyl-functionalized graphene oxide (FGO) construct simple fluorescence quenching platform. FGO CdTe QDs modified with aptamers cause FRET effect produces yellow-green quenching. When present, form complexes it leave platform, resulting in recovery. used aptasensor wide detection range 0.05 150 ng/mL low limit (LOD) 8.2 pg/mL. The average recoveries peanut pure milk samples ranged from 94.5% 107.0%. also exhibited advantages operation, cost, good stability. reported here can thus serve as candidate rapid AFB1.
