“…Gaseous analytes were detected with TiO 2 nanoparticles in the composite structure. TiO 2 is advantageous as it can endure temperatures as high as 600 • C, is abundant, has good stability, and is easy to process [94]. After the individual components of the composite material were prepared, the ternary nanocomposite was designed through physical methods such as grinding and mixing.…”

With a rising emphasis on public safety and quality of life, there is an urgent need to ensure optimal air quality, both indoors and outdoors. Detecting toxic gaseous compounds plays a pivotal role in shaping our sustainable future. This review aims to elucidate the advancements in smart wearable (nano)sensors for monitoring harmful gaseous pollutants, such as ammonia (NH3), nitric oxide (NO), nitrous oxide (N2O), nitrogen dioxide (NO2), carbon monoxide (CO), carbon dioxide (CO2), hydrogen sulfide (H2S), sulfur dioxide (SO2), ozone (O3), hydrocarbons (CxHy), and hydrogen fluoride (HF). Differentiating this review from its predecessors, we shed light on the challenges faced in enhancing sensor performance and offer a deep dive into the evolution of sensing materials, wearable substrates, electrodes, and types of sensors. Noteworthy materials for robust detection systems encompass 2D nanostructures, carbon nanomaterials, conducting polymers, nanohybrids, and metal oxide semiconductors. A dedicated section dissects the significance of circuit integration, miniaturization, real-time sensing, repeatability, reusability, power efficiency, gas-sensitive material deposition, selectivity, sensitivity, stability, and response/recovery time, pinpointing gaps in the current knowledge and offering avenues for further research. To conclude, we provide insights and suggestions for the prospective trajectory of smart wearable nanosensors in addressing the extant challenges.

“…The fabricated sensor exhibited good sensitivity, selectivity, fast response time and long-term stability of 60 days. Muthusamy et al, 96 recently reported a new ternary conducting polymer composite of polypyrrole (PPy), prussian blue (PB), titanium dioxide (TiO 2 ), PPy-PB-TiO 2 for fiber optic gas sensing applications. The gas sensing properties of this sensor were investigated upon ethanol, ammonia, and acetone with varying concentrations (0-500 ppm).…”

Increased environmental pollution is becoming one of the greatest problem the world is facing nowadays causing irreparable damage to the earth. Because of their novel and tunable physicochemical properties, nano materials have attracted great attention among researchers as promising materials to combat environmental challenges. Developing nanotechnology have triggered a great deal of interest in these structures for pollution monitoring and treatment, enabling new technologies for identifying and addressing environmental problems. Even though achieving environmental pollution control is a challenging task using conventional materials, revolutionary progress has been observed with the advancements in nanotechnology, showing that precisely modified nano materials can be used for purposes such as treatment of polluted atmosphere, industrial and domestic wastewater, natural water, and soil. In this paper we review and discuss the environmental applications of nano materials as nano sensors employed for combating atmospheric and aquatic pollution. Keywords: enviro

“…Large surface area of polymeric materials enable gas molecules to adsorb in a better way. Various metals based gas sensors have been reported previously for gas sensing (Sharma and Kim, 2018;Zhang et al, 2019b) but efficacy of these devices was improved by synthesizing the nanohybrids of inorganic materials with polymers (Muthusamy et al, 2021;Sonwane et al, 2019). Various inorganic metal oxides may perform as catalyst to decompose gases in free radicals and facilitate their combination with oxygen having functional moieties on polymeric surfaces, and hence, showing great response towards such gases (Karaduman et al, 2017).…”

“…Therefore, this study presented a rapid, selective, ultrasensitive and reversible ammonia gas sensor under high humid conditions for clinical diagnosis. In addition to this, polypyrrole (PPy) has been utilized to prepare nanohybrid sensors for ammonia gas detection at room temperature by incorporating several nanomaterials such as TiO 2 (Muthusamy et al, 2021), SnO 2 -GNR (Hsieh et al, 2021), NiO (Thi Hien et al, 2021), Ag-Ag 2 O (Shoeb et al, 2021), graphene oxide (Shahmoradi et al, 2021), WO 3 (Albaris and Karuppasamy, 2020), V 2 O 5 -WO 3 (Amarnath et al, 2020), ZnO (P. , Au (Li et al, 2020c), etc. Abun and colleagues reported the fabrication of ammonia gas sensor through polymethyl-methacrylate (PMMA) supported exfoliation of molybdenum disulfide (MoS 2 ) multi-layered nano-sheets by ultrasonication technique (Abun et al, 2020).…”
