“…However, in their review paper, they only focused on room temperature gas sensors and in addition to acetone, they discussed other types of gases. Alizadeh et al [53] presented a good and comprehensive review paper about acetone gas sensors. However, they have not focused on metal oxide gas sensors, but all other types of gas sensors are discussed.…”

Acetone is a well-known volatile organic compound that is widely used in different industrial and domestic areas. However, it can have dangerous effects on human life and health. Thus, the realization of sensitive and selective sensors for recognition of acetone is highly important. Among different gas sensors, resistive gas sensors based on nanostructured metal oxide with high surface area, have been widely reported for successful detection of acetone gas, owing to their high sensitivity, fast dynamics, high stability, and low price. Herein, we discuss different aspects of metal oxide-based acetone gas sensors in pristine, composite, doped, and noble metal functionalized forms. Gas sensing mechanisms are also discussed. This review is an informative document for those who are working in the field of gas sensors.

“…VOCs are metabolic products that enter the bloodstream and are released into the air via blood, urine, feces, skin and breath (Amann et al, 2014). The use of volatile organic compounds (VOCs) has been widely reported throughout literature as a means by which certain diseased states may be identified [ [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] ]. Analytical instruments have been tested and show promise for their use as effective screening tools [ 20 ].…”

The novel coronavirus SARS-CoV-2, since its initial outbreak in Wuhan, China has led to a worldwide pandemic and has shut down nations. As with any outbreak, there is a general strategy of detection, containment, treatment and/or cure. The authors would argue that rapid and efficient detection is critical and required to successful management of a disease. The current study explores and successfully demonstrates the use of canines to detect COVID-19 disease in exhaled breath. The intended use was to detect the odor of COVID-19 on contaminated surfaces inferring recent deposition of infectious material from a COVID-19 positive individual. Using masks obtained from hospitalized patients that tested positive for COVID-19 disease, four canines were trained and evaluated for their ability to detect the disease. All four canines obtained an accuracy >90% and positive predictive values ranging from ∼73 to 93% after just one month of training.

“…Real-time breath analysis presents many potential benefits. As such, there are various technologies such as electrochemistry [ 10 ], gas chromatography (GC) [ 11 ], mass spectrometry (MS) [ 11 , 12 ], and optical spectroscopy [ 13 , 14 ] that have been investigated and published over the last few decades. Currently, the conventional laboratory-based techniques for analyzing volatile organic compounds (VOCs) are thermal desorption (TD) GC-MS and nuclear-magnetic-resonance (NMR) [ 15 , 16 , 17 ].…”

A plasmonic sensing platform was developed as a noninvasive method to monitor gas-phase biomarkers related to cystic fibrosis (CF). The nanohole array (NHA) sensing platform is based on localized surface plasmon resonance (LSPR) and offers a rapid data acquisition capability. Among the numerous gas-phase biomarkers that can be used to assess the lung health of CF patients, acetaldehyde was selected for this investigation. Previous research with diverse types of sensing platforms, with materials ranging from metal oxides to 2-D materials, detected gas-phase acetaldehyde with the lowest detection limit at the µmol/mol (parts-per-million (ppm)) level. In contrast, this work presents a plasmonic sensing platform that can approach the nmol/mol (parts-per-billion (ppb)) level, which covers the required concentration range needed to monitor the status of lung infection and find pulmonary exacerbations. During the experimental measurements made by a spectrometer and by a smartphone, the sensing examination was initially performed in a dry air background and then with high relative humidity (RH) as an interferent, which is relevant to exhaled breath. At a room temperature of 23.1 °C, the lowest detection limit for the investigated plasmonic sensing platform under dry air and 72% RH conditions are 250 nmol/mol (ppb) and 1000 nmol/mol (ppb), respectively.
