| Abstract: | In this study, a photoelectrochemical sensor for the detection of glucose was developed by combining the unique properties of NH2-MIL-125 and Ti3C2 film. The relationship between the microstructure of the samples and their performance in glucose detection was investigated. Experimental results demonstrated a linear decrease in the differential pulse voltammetry current of the Ti3C2/NH2-MIL-125-3 photoelectrochemical sensor with increasing glucose concentration. Below 200 μM, the relationship between DPV current and glucose concentration was found to be: I (mA) = − 3.86667 × 10–8·cg (μM) + 3.66 × 10–4 (cg denoted as the concentration of glucose). Above 200 μM, the relationship was: I (mA) = − 4.03049 × 10–8·cg (μM) + 3.68268 × 10–4. Density functional theory calculations were in agreement with the experimental data. The Ti3C2/NH2-MIL-125-3 photoelectrochemical sensor demonstrates exceptional glucose detection capability. This technology has the potential to advance the development of MXenes/MOFs-based photoelectrochemical biosensors. [ABSTRACT FROM AUTHOR] |
