Abstract
A bimodal sensor able to effectively detect cetirizine, an antihistaminic drug, was proposed. The device is based on the catalytic properties of silver and the photoactivity of TiO2 and can be used as dual electrochemical-photoelectrochemical sensor, with good performances in cetirizine quantification both through the molecule's reduction and its photo-oxidation, with limits of detections of (3.2 ± 0.1) and (1.03 ± 0.08) µM, respectively. The use of these two materials allows for greater stability, robustness, and reusability compared to using two separate electrodes. Furthermore, a comparison of the results obtained with the two techniques can help in identifying and eliminating the effects of interferents, thus increasing the reliability of the detection.
期刊介绍：
Electroanalysis is an international, peer-reviewed journal covering all branches of electroanalytical chemistry, including both fundamental and application papers as well as reviews dealing with new electrochemical sensors and biosensors, nanobioelectronics devices, analytical voltammetry, potentiometry, new electrochemical detection schemes based on novel nanomaterials, fuel cells and biofuel cells, and important practical applications.
Serving as a vital communication link between the research labs and the field, Electroanalysis helps you to quickly adapt the latest innovations into practical clinical, environmental, food analysis, industrial and energy-related applications. Electroanalysis provides the most comprehensive coverage of the field and is the number one source for information on electroanalytical chemistry, electrochemical sensors and biosensors and fuel/biofuel cells.
