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.

“…The GO-ZnO crystallography plane coincides with zinc wurtzite type diffraction peaks, as validated by JCPDS File Card No. 36-1451. , The high intensity (101) suggests an anisotropic nature and the crystallites’ preferred direction of ZnO. The sample’s crystallinity and grain size both improved as the annealing temperature was increased.…”

A human framework needs a careful monitoring of drug concentration which imparts unfavorable condition to human health. Among the various antibiotics, sulfamethoxazole (SMX) has been determined to be a typical antibiotic that is used to treat urinary tract infections, toxoplasmosis, pneumonia, and skin and soft tissue infections. Herein, we report an electrochemical sensing platform using graphene oxide (GO), and nanostructured zinc oxide (ZnO) are used for the detection of SMX. In this study, the working electrodes, GO is modified on FTO using a dip coating technique and on ZnO nanostructures, using a hydrothermal coating method. Finally, GO was dip-coated on FTO in order to obtain a seed layer and the ZnO nanostructure was developed using a hydrothermal method, thus obtaining as GO-ZnO/FTO as a working electrode for SMX detection. Hence, our developed electrodes aimed for high sensitivity that was evidenced to detect SMX at high potential windows. Prior to sensing analysis, the physical and morphological properties of developed electrodes were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods. The performance of GO/FTO, ZnO/FTO, and GO-ZnO/FTO was probed by cyclic voltammetry (CV) and current−voltage characteristics (I−V). It was noticed that GO-ZnO/FTO found to exhibit a flower-like structure morphology with effective surface area and active sites for anchoring adsorbate molecules, thus leading to the production of amplified current signals in high potential windows. Under optimized conditions, the designed sensor provided the SMX detection with nanomolar and picomolar limit of detection (0.182 ng/L, 4.8 pg/L, and 0.0949 ng/L), respectively. Besides the specificity, stability and reliability studies were tested for electrodes in multiple real-time water samples for designed sensors. The experimental results of developed sensors show that it has an excellent electron transfer system on the sensor surface among the practical sensors reported for drug applications.

“…Various methods of determining FA in gas samples have been reported, including spectrophotometry (Gorrotxategi-Carbajo et al, 2013), electrochemistry (Zhang et al, 2020a(Zhang et al, , 2020b, chemiluminescence (Song et al, 2009), fluorescence (Liu et al, 2019;Wang et al, 2021), and imaging (Liu et al, 2019) techniques. Various materials have been employed for FA detection, such as ZIF-90-LW (Wen et al, 2020), naphthalimide (Bi et al, 2018), CuO/Cu/TiO 2 nanotubes (Zhang et al, 2020a(Zhang et al, , 2020b, egg white/ZnO (Padmalaya et al, 2022), carbon dots (CDs) (Qu et al, 2020;Lin et al, 2022;Kim et al, 2021;Liu et al, 2021;Li et al, 2023;Zhao et al, 2022;Hu and Gao, 2020), SnSO 4 /ZnO (Chang et al, 2018), C 60 -encapsulated TiO 2 (Gakhar and Hazra, 2021), ZnSnO 3 porous nanostructures (Du et al, 2021), and RGO/HA-HCl (Zhou et al, 2020). However, there are still some limits for these methods such as high cost, high toxic reagent use, as well as the only use in aqueous media or vapor.…”
