Cover Story: The development of non-invasive diagnostics that employ chemoresistive gas sensors to detect disease biomarkers in human breath has been a hot research topic in materials science. This growing interest is largely due to the synergic effects between the sensor performance and semiconducting metal-oxide-sensing layer. Thus, the manufacturing of high-performance gas sensor devices is directly related to the surface engineering of the selected semiconducting metal-oxide-employing advanced synthesis methods. In this study, we report the acetone-biomarker-sensing performance of well-faceted h-MoO3 microrods synthesized by an ultrafast microwave-assisted hydrothermal route. View this paper.
