Electrochemical bio-sensor of caffeine in food beverages on using silver vanadium oxide decorated in graphitic carbon nitride (AgVO@g-CN) Nano composite modified glassy carbon electrode
The silver vanadate AgVO@g-CN was synthesized by the Co-precipitation method for the first time. The electrocatalytic potential of the AgVO@g-CN nanocomposite is investigated using cyclic voltammetry and differential pulse voltammetry to detect caffeine (CAF). The linear relationship between peak current and CAF concentration has been determined to be in the 6.5 to 255 μM wide linear range, with a lower detection limit of 0.038 μM. The sensitivity of produced electrode was 5.87 μAμM−1 cm−1. The successful application of the modified AgVO@g-CN nanocomposite electrode for CAF detection demonstrates operational stability, and the novel technique displayed good repeatability and reproducibility. Caffeine levels in commercial coffee, Red Bull, and Coca-Cola were successfully determined using the proposed sensor. The results obtained clearly show the capability of sensing and possible application of AgVO@g-CN nanocomposite for real-time electrochemical detection of CAF.
期刊介绍：
Sensing and Bio-Sensing Research is an open access journal dedicated to the research, design, development, and application of bio-sensing and sensing technologies. The editors will accept research papers, reviews, field trials, and validation studies that are of significant relevance. These submissions should describe new concepts, enhance understanding of the field, or offer insights into the practical application, manufacturing, and commercialization of bio-sensing and sensing technologies.
The journal covers a wide range of topics, including sensing principles and mechanisms, new materials development for transducers and recognition components, fabrication technology, and various types of sensors such as optical, electrochemical, mass-sensitive, gas, biosensors, and more. It also includes environmental, process control, and biomedical applications, signal processing, chemometrics, optoelectronic, mechanical, thermal, and magnetic sensors, as well as interface electronics. Additionally, it covers sensor systems and applications, µTAS (Micro Total Analysis Systems), development of solid-state devices for transducing physical signals, and analytical devices incorporating biological materials.
