Abstract

This study aims to discuss the synthesis and fabrication of SnO-InO-based thick-films and their biosensing applications. The structural characterization of SnO-InO nanocomposites was performed using X-ray diffraction, Raman spectroscopy and transmission electron microscopy. Furthermore, the screen-printing technology was used in the fabrication of conductive electrodes to form an interdigitated capacitive structure, and the sensor layer based on the mixture of SnO and InO. Moreover, the sensing performance of the developed structure was tested using () and () bacteria. In addition, the validation of sensing characteristics was performed by electrochemical impedance spectroscopic and self-resonant frequency analysis. Finally, the sensing properties were analyzed for two consecutive days, and changes in both and pathogens growing media were also studied.
