CuMoO/TiCTx nanocomposite layers perform as an ultrasensitive electrochemical sensor for the detection of antioxidant rutin.

The focus of this paper is laid on synthesizing layered compounds of CuMoO and TiCTx using a simple wet chemical etching method and sonochemical method to enable rapid detection of rutin using an electrochemical sensor. Following structural examinations using XRD, surface morphology analysis using SEM, and chemical composition state analysis using XPS, the obtained CuMoO/TiCTx nanocomposite electrocatalyst was confirmed and characterized. By employing cyclic voltammetry and differential pulse voltammetry, the electrochemical properties of rutin on a CuMoO/TiCTx modified electrode were examined, including its stability and response to variations in pH, loading, sweep rate, and interference. The CuMoO/TiCTx modified electrode demonstrates rapid rutin sensing under optimal conditions and offers a linear range of 1 µΜ to 15 µΜ, thereby improving the minimal detection limit (LOD) to 42.9 nM. According to electrochemical analysis, the CuMoO/TiCTx electrode also demonstrated cyclic stability and long-lasting anti-interference capabilities. The CuMoO/TiCTx nanocomposite demonstrated acceptable recoveries when used to sense RT in apple and grape samples. In comparison to other interfering sample analytes encountered in the current study, the developed sensor demonstrated high selectivity and anti-interference performance. As a result, our research to design of high-performance electrochemical sensors in the biomedical and therapeutic fields.
