Fabrication of a non-enzymatic photoelectrochemical sensor based on a BiOBr-CuO nanocomposite for detecting Glucose and Tetracycline
In this study, we developed a non-enzymatic photoelectrochemical sensor using a BiOBr-CuO (BiCu) electrode, which was synthesized via solvothermal method. The sensor was designed for the simultaneous detection of glucose and tetracycline. Our study revealed that the BiCu electrode exhibited superior...

| description | In this study, we developed a non-enzymatic photoelectrochemical sensor using a BiOBr-CuO (BiCu) electrode, which was synthesized via solvothermal method. The sensor was designed for the simultaneous detection of glucose and tetracycline. Our study revealed that the BiCu electrode exhibited superior photocurrent generation compared to the individual BiOBr and CuO electrodes, as demonstrated by cyclic voltammetry and amperometric studies. The BiCu electrode's performance has increased due to the formation of a heterojunction between CuO and BiOBr, which modifies the UV–visible DRS spectrum and generates an internal electric field that reduces the recombination of the photogenerated carriers. This enhanced the capability of the sensor to detect both glucose and tetracycline. We successfully applied the proposed photoelectrochemical sensor to detect human blood glucose level. The sensitivity and detection limit for glucose and tetracycline are 0.1342 mAmM−1cm−2, 0.014 mM and 1.7234 mAmM−1cm−2, 2.0 μM respectively. Thus, the fabricated electrode demonstrated exceptional catalytic activity, high selectivity, good reproducibility, wide linear detection range, low limit of detection,long-term stability, ease of synthesis, good stability and notable selectivity for detecting both glucose and tetracycline This suggests that the BiCu electrode has significant potential as a reliable platform for the detection of glucose and tetracycline. |
