“…In a similar manner to the detection of DCM, quartz crystal microbalance (QCM) techniques were also exploited for the detection of limonene and α-pinene. In detail, a sensor for the detection of limonene was prepared using a QCM chip as the sensor transducer and ethyl cellulose as the sensing material [ 110 ]. The use of ethyl cellulose (EC) is of particular interest since EC is derived from cellulose, i.e., the most renewable natural polymer on Earth [ 111 ].…”

The efficient and selective detection of volatile organic compounds (VOCs) provides key information for various purposes ranging from the toxicological analysis of indoor/outdoor environments to the diagnosis of diseases or to the investigation of biological processes. In the last decade, different sensors and biosensors providing reliable, rapid, and economic responses in the detection of VOCs have been successfully conceived and applied in numerous practical cases; however, the global necessity of a sustainable development, has driven the design of devices for the detection of VOCs to greener methods. In this review, the most recent and innovative VOC sensors and biosensors with sustainable features are presented. The sensors are grouped into three of the main industrial sectors of daily life, including environmental analysis, highly important for toxicity issues, food packaging tools, especially aimed at avoiding the spoilage of meat and fish, and the diagnosis of diseases, crucial for the early detection of relevant pathological conditions such as cancer and diabetes. The research outcomes presented in the review underly the necessity of preparing sensors with higher efficiency, lower detection limits, improved selectivity, and enhanced sustainable characteristics to fully address the sustainable manufacturing of VOC sensors and biosensors.

“…One of the common solutions ensuring the health and safety of the station’s operation is carrying out measurements that detect gas under a hood [ 36 ]. Another popular and safe method of neutralising gas mixtures used for sensor measurements is the neutralisation of hazardous gases in a bubbler filled with a solution that reacts with the gases used [ 34 , 63 ]. Such a solution has been used by, among others, Barauskas et al [ 64 ] using 0.5 mol NaOH to neutralise SO 2 and CO 2 .…”

“…Another popular solution is the use of a burner to burn the flammable gas [ 65 ]. Some articles only provide brief information on gas neutralisation, e.g., with the use of adsorbers ( Figure 4 and Figure 5 ) [ 63 , 66 ]. By contrast, in the case of using a sensor-measuring system outside, when testing the presence of gases in the atmosphere (surroundings), it is enough to use a fan to force the gases to move within the measuring chamber (in the vicinity of the sensor).…”

“…For this reason, materials that do not react with oxidizing and reducing gases are used to make the elements of the sensor test set-ups. For example, measuring cells are made of glass (e.g., borosilicate glass [ 51 ]), acrylic glass [ 69 ], stainless steel [ 17 , 20 , 62 , 70 ], aluminium, Teflon [ 63 ] and various other plastics [ 66 ]. These are non-reactive materials, and additionally, they are resistant to high temperatures that can change over a wide range.…”

This paper introduces a novel wearable flexible gas sensor designed specifically for the detection of d‐limonene. The sensor utilizes materials recognized for their high efficiency‐to‐cost ratio, notably polyaniline (PANI) combined with carboxylated multiwalled carbon nanotubes (MWCNT) and graphene oxide (GO) as sensing layers. The study conducts a comprehensive analysis of the nanocomposite layers, examining their functional groups, morphology, topography, thickness, crystallinity, thermal behavior, surface area, as well as the size and volume of their pores. This examination showed distinctions among the nanocomposite layers. PANI/GO exhibited larger pore size and thickness, while PANI/MWCNT_COOH demonstrated a higher surface area. The analysis of thermal stability demonstrated that the film employing the DBSA dopant exhibited the lowest stability. Morphological characterizations showed a globular structure for PANI, tubular characteristics for PANI/MWCNT_COOH, and a flat nature for PANI/GO. When detecting d‐limonene, nanocomposite films doped with HCl demonstrated notably superior response levels. The gas sensors exhibited high sensitivity (>2.24 mV/ppm), a narrow range for the limit of detection (0.12–0.52 ppm), and excellent reversibility, stability, and selectivity. These findings suggest the possibility of broadening the application of gas sensors to monitor additional volatile compounds, with a particular emphasis on the online monitoring of agricultural products.
