Prof. Merkoi is Co-Editor in Chief of Biosensors and Bioelectronics, the principal international journal devoted to research, design development and application of biosensors and bioelectronics, member of editorial board of Electroanalysis, Microchimica Acta and other journals. The chemical adsorption process can be explained by the following reactions: When SnO2 sensor contacts with the measured gas, its resistance will change according to the oxidation or reduction characteristics of the gas. The sensing mechanism of the SnO2 sensor reacting with these gases can be represented by the following path, where O is taken as an example (Lian et al., 2017; Zhu et al., 2019): With the development of semiconductor gas-sensing materials, it has been the focus of research to enhance their gas-sensing properties for gas detection.
