摘要

Here, okra extract was successfully utilized for the green synthesis of magnetic CoFe2O4 nanoparticles, which were subsequently decorated onto a g-C3N4 matrix. Characterization techniques such as FT-IR, XRD, SEM, and EDX confirmed the successful formation of the CoFe2O4@g-C3N4 nanocomposite. The bio-synthesized materials were used to modify a glassy carbon electrode (GCE), resulting in the CoFe2O4@g-C3N4/GCE sensor, which demonstrated excellent electro-catalytic performance for morphine detection. According to DPV, the developed sensor exhibits a wide dynamic range (0.01–250 µM), and a low limit of detection (3 S/m, 94.017 nM). The prepared electrode combines strong selectivity with reliable reproducibility and stability. Further, its successful performance in real biological samples highlights its promise for practical analytical applications.
