Au-NPs/ZnO Single Nanowire Nanosensors for Health Care Applications

Abstract

Herein, the room temperature gas sensing properties of a device fabricatedbased on an individual gold nanoparticles (AuNPs)-functionalized zinc oxide nanowire (ZnO NW) is reported. The Au-NPs/ZnO nanowires were depositedusing theelectrochemical approachin a classical three-electrode electrochemical cell. The dual beam focused ion beam/scanning electron microscopy (FIB/SEM) was usedto integrate the singlenanostructuresinto gas sensing nanodevices.The results are promising for futureapplications in monitoring H2gas for health care applications and clinical breath analysis.
