Performances and Biosensing Mechanisms of Interdigitated Capacitive Sensors Based on the Hetero-mixture of SnO and InO.

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.
