Abstract:
... In this paper a new aptasensor with high-sensitivity, and high-specificity for detection of diazinon, was discovered, based on fluorescence resonance energy transfer (FRET) between quantum dot (QD) as a donor and graphene oxide (GO) as an acceptor. l-cysteine capped CdS QDs/DF20 aptamer bioconjugates were successfully synthesized. GO was also attached to aptamers and photoluminescence quenching wa ...
