a Schematic illustrations of an antifouling gas sensor based on the hierarchical reentrant GNW-ZNS structure. b The fabrication process of the GNW-ZNS-based sensor: vertical GNWs were prepared on a Si/SiO2 substrate, followed by ZnO seed layer deposition using magnetron sputtering, hydrothermal growth of ZnO nanospikes, and annealing. GNW-ZNS was further integrated and used as a gas sensor for NH3 detection
