    摘要:In this study, N-(4-Aminobutyl)-N-ethylisoluminol (ABEI) and CoFe2O4 nanoparticle functionalized graphene hybrids (ABEI/CoFe2O4/GNs) were synthesized for the first time via a hydrothermal reaction and π–π stacking using ABEI as a chemiluminescence (CL) reagent and CoFe2O4 magnetic nanoparticles (MNPs) as a catalyst and magnetic carrier. The as-prepared ABEI/CoFe2O4/GNs demonstrated a good magnetic separation performance, which could be used as a separation tool for the purification of ABEI/CoFe2O4/GNs. Moreover, the as-prepared ABEI/CoFe2O4/GNs exhibited outstanding CL activity and good stability when reacted with H2O2 in alkaline solution; the CL intensity was about 80 times higher than that of ABEI/GNs. The ABEI/CoFe2O4/GNs also exhibited good electrochemiluminescence (ECL) activity in alkaline and near-neutral conditions without any additional co-reactant. The excellent CL/ECL efficiency of the ABEI/CoFe2O4/GNs was attributed to the CoFe2O4 MNPs immobilized on the surface of graphene, which catalyzed the decomposition of H2O2 to generate O2˙− and HO˙, accelerating the CL/ECL reaction. Owing to their good magnetic properties, unique CL/ECL performance and good stability, as well as easy assembly and biocompatibility of graphene, the as-prepared ABEI/CoFe2O4/GNs could be used as an ideal platform for constructing biosensors and bioassays.
