Fig. 5: Gas sensing performance against biofouling.
From: Anti-biofouling NH3 gas sensor based on reentrant thorny ZnO/graphene hybrid nanowalls
a Bar graphs of the relative response of GNW-ZNS- and GNW-based sensors to different analytes at RT. b Schematic of the biofouling test of GNW-ZNS. Samples were placed on a tilted glass slide, and a bacterial suspension (2 ml) was deposited directly onto the sample surface. The biofouled samples were fabricated into sensors after rinsing and drying, and the gas sensing properties were recorded. c Gas response curves of biofouled GNW-ZNS- and GNW-based sensors to NH3 (400 ppm) at RT
