Tóm tắt

Enrofloxacin (ENR) residues in animal derived foods are harmful to human health. A molecularly imprinted electrochemiluminescence sensor was constructed for ENR detection utilizing a self-enhanced quasi-three-dimensional luminescent-composite of boron nitride quantum dots/nitrogen-doped mesoporous carbon crosslinked with copper nanowires (BNQDs/NMC-CuNWs). One-dimensional CuNWs with near-infrared electrochemiluminescence (NIR-ECL) properties were inserted into the electroactive layer of two-dimensional NMC to form quasi-three-dimensional NMC-CuNWs, which inhibited the aggregation of CuNWs and increased the electron and active ion transport rates. BNQDs were also embedded into the NMC-CuNWs network as co-reactant accelerators and antioxidants. A molecularly imprinted polymer containing bifunctional monomers enabled the specific detection of ENR. The detection range of ENR was 1.00 × 10
