Summary
Sensors, biosensors, and chemical sensors have revolutionized modern technology, providing significant benefits for quality of life and product control. Biosensors, in particular, have seen significant investment in research and development, with a projected global market value of 27 billion US dollars by 2022. These sensors are used to detect a range of analytes, including glucose levels, pathogens, pollutants, drugs, and more. The key feature of these sensors is their ability to accurately differentiate the desired analyte. In this study, a new evaluation methodology is introduced to assess the response of a sensor. The differential method uses simple mathematics to analyze the response of a sensor unit in comparison to a control unit, eliminating the need for complex calculations. The new metric was tested to differentiate between caffeine, NaCl, HCl, sucrose, and monosodium glutamate. The sensor unit consisted of electrodes, each with a unique polymeric film immobilized on its surface, including PANI, POMA, P3HT, PVK-PBD, PVK, and P3HT-PMMA films. The study was conducted at two levels of substance concentration, except for HCl, which was tested at concentrations of 0.01 and 0.1 mM. A second test was performed to evaluate the efficiency of the differential method using sensor units with metal oxide films on their surface, including ZnO, IZO, AZO, and ITO. The units were used to distinguish between organic solvents, such as Methanol, Ethanol, Toluene, and 2-Methoxyethanol, as well as their mixtures. The differential method was found to be successful in both studies, with a 3D graph created to provide a visual comparison to Principal Component Analysis (PCA).Overall, the results of this study highlight the effectiveness of the differential method in evaluating the response of sensors and biosensors, offering a simpler and more reliable approach to sensor analysis. With the increasing demand for advanced biosensors and the growing market, this research holds significant potential for further development and application.
