The objective of this research axis is to develop sensors that benefit from the nanowire advantages for detection while being easy to integrate into electrical devices and compatible with integration on CMOS integrated circuits. Thus, it becomes possible to couple detection, reading and signal conditioning for a reduced footprint. This axis is based on the materials developed by the research theme "Wet Chemistry and Surface Functionalization" (link).
Thus, our unique international expertise encompasses the fabrication, the functionalization and the integration of two-dimensional (2D) Si nanonets for electrical DNA detection and 2D ZnO nanonets for electrical acetone gas detection.A nanonet is a two-dimensional network of randomly oriented nanowires (link). We focus our research on semiconducting nanonets, particularly those based on Si and ZnO nanowires, so that their electrical properties are changed when events occur on their surfaces. The events we are currently interested in are DNA hybridization, protein recognition or acetone adsorption, the latter being a marker of diabetes.
