Abstract

<jats:sec> <jats:title>Background::</jats:title> <jats:p>An important antioxidant, ascorbic acid, must be detected in several industrial samples collected from food, pharmaceuticals, and water treatment plants. Herein, we reported a method to produce a bimetallic copper-silver (Cu-Ag) nanocomposite and used it in the development of very sensitive and selective electrochemical sensor for the detection of ascorbic acid.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods::</jats:title> <jats:p>A simple chemistry concept was used during the synthesis process to reduce the cost while minimizing the use of dangerous chemicals and minimizing the environmental impact. The Strobilanthes kunthiana leaves extract effectively reduced the copper and silver ions, resulting in the creation of an extremely stable and evenly distributed Cu-Ag nanocomposite.</jats:p> </jats:sec> <jats:sec> <jats:title>Results::</jats:title> <jats:p>As-prepared bimetallic Cu-Ag nanocomposite exhibited outstanding electrochemical activity against ascorbic acid oxidation. The nanocomposite was examined using field emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), elemental mapping (EMap) and X-ray diffraction analysis (XRD) to ascertain its composition, structure, and stability. Using cyclic voltammetry (CV), the electrochemical performance of the nanocomposite and also the detection of ascorbic acid were carried out. The bimetallic Cu-Ag nanocomposite also exhibited better long-term stability and fouling resistance, making it appropriate for use in real-world applications and complex sample matrices.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusion::</jats:title> <jats:p>The bimetallic Cu-Ag nanocomposite coated electrode was used to detect the concentration of ascorbic acid by amperometry. As a result, this study offered a simple chemical method for creating a bimetallic copper-silver nanocomposite with superior electrochemical qualities for the accurate detection of ascorbic acid.</jats:p> </jats:sec> <jats:sec> <jats:title>conclusion:</jats:title> <jats:p>Its potential use as an electrochemical sensor for the detection of ascorbic acid opens doors for a variety of industries, including biological diagnostics, judging the quality of food, and environmental monitoring. As a result, this study offers a green method for creating a bimetallic copper-silver nanocomposite with superior electrochemical qualities for the accurate detection of ascorbic acid. The created nanocomposite has a lot of potential for improving ascorbic acid detection methods while upholding sustainable material synthesis.</jats:p> </jats:sec> <jats:sec> <jats:title>other:</jats:title> <jats:p>NA</jats:p> </jats:sec>
