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

Sulfur dioxide (SO2) is one of the most hazardous and common environmental pollutants. However, development room-temperature SO2 sensors seriously lagging behind that other toxic gas due to their poor recovery properties. In this study, a light-assisted sensor based on polyaniline (PANI) Ag nanoparticle-comodified tin nanostructures (Ag/PANI/SnO2) was developed exhibited remarkable sensitivity excellent The response Ag/PANI/SnO2 (20.1) 50 ppm under 365 nm ultraviolet (UV) light illumination at 20 °C almost 10 times higher than pure SnO2 sensor. Significantly, UV-assisted had rapid time (110 s) (100 SO2, but in absence light, performance or were even severely irreversibly deactivated by SO2. also selectivity, superior reproducibility, satisfactory long-term stability room temperature. increased charge carrier density, improved charge-transfer capability, active surface revealed electrochemical measurements endowed with high sensitivity. Moreover, light-induced formation hot electrons high-energy state significantly facilitated

The rapid development of the human population has created demand for an increase in production food various fields, such as vegetal, animal, aquaculture, and processing. This causes increment use technology related to production. An example this is gases many steps treatment, preservation, processing, ripening. Additionally, are used across value chain from packaging storage transportation beverage industry. Here, we focus on long-standing recent advances gas-based Although studies have been conducted identify chemicals biological contaminants foodstuffs, gas sensors a vital role. capable detecting presence target ethylene (C2H4), ammonia (NH3), carbon dioxide (CO2), sulfur (SO2), ethanol (C2H5OH) received significant interest researchers, not only but also indicator quality food. Therefore, discuss latest practical focused these terms sensor response, sensitivity, working temperatures, limit detection (LOD) assess relationship between emitted or foods sensors. Greater given heterostructured at low temperatures flexible layers. Future perspectives sensing monitoring eventually stated. We believe that review article gathers valuable knowledge researchers interested sciences development.
