Sensitive Detection of Hesperidin Based on CN-MWCNTs/Ti3C2 Composite Modified Electrode

In this study, carbon nitride-multiwalled carbon nanotubes/ MXenes (CN-MWCNTs/Ti 3 C 2 ) nanocomposites with excellent properties were synthesized by a convenient method and characterized using various methods. By modifying the CN-MWCNTs/Ti 3 C 2 composites on glassy carbon electrode, an electrochemical sensor capable of sensitive and rapid detection of hesperidin (HPD) was established. Under the optimal conditions, the sensor showed excellent detection performance for HPD (0.1 M PBS (pH 7.0)). The linear range was 0.05–503 μM, and the detection limit (S/N = 3) was 0.017 μM. In addition, the sensor has the advantages of good immunity to interference, stability and reproducibility.
