The CdTe quantum dots (QDs), graphene nanocomposite (CdTe-G) and dextranCFe3O4 magnetic nanoparticles have been synthesized for developing an ultrasensitive electrochemiluminescence (ECL) immunoassay for Carcinoembryonic antigen 19-9 (CA 19-9) in serums. of human serum were tested, and the results were compared with a time-resolved fluorescence assay (TRFA). The novel immunoassay provides a stable, specific and highly… Continue reading The CdTe quantum dots (QDs), graphene nanocomposite (CdTe-G) and dextranCFe3O4 magnetic
