Zinc Oxide‐Based Acetone Gas Sensors for Breath Analysis: A Review

Abstract: Acetone is one of the toxic, explosive, and harmful gases. It may cause several health hazard issues such as narcosis and headache. Acetone is also regarded as a key biomarker to diagnose several diseases as well as monitor the disorders in human health. Based on clinical findings, acetone concentration in human breath is correlated with many diseases such as asthma, halitosis, lung cancer, and diabetes. Thus, its investigation can become a new approach for health monitoring. Better management at the early sta… Show more

“…[18,19] Zinc oxide (ZnO) is widely used in many applications such as gas sensors, solar cells, photocatalysis, medicines, lightemitting diodes, laser diodes, chemical and biosensors. [20][21][22][23] ZnO is one of the most studied photocatalyst due to its low cost, high photosensitivity, non-toxic nature, environmentally friendly features, and suitable conduction band and valence band positions with enough redox potential for the production of hydroxyl * OH and * O 2 free radicals. However, large band gap and rapid charge recombination limit its photocatalytic performance.…”

“…ZnO, a typical metal oxide semiconductor (MOS), has potential uses in the detection of hazardous gases because of its wide bandgap, n-type transport characteristic, and high electrical performance. Meanwhile, doping ZnO materials is an efficient approach to increase their sensing capability [7,8].…”
