Individual Optical Multi-Gas Sensors as Next Generation Second-Order Unobtrusive and Continuous Operation Analytical Instruments

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 18, 2025

Simple, single-output (zero-order) gas sensors have established applications for industrial and residential safety. However, in detection of low levels analyte gases diverse chemical backgrounds, zero-order often poor performance, cancelling out their small size low-cost advantages over traditional analytical instruments. Thus, with one two independent variables (first- second-order sensors) are under development to meet contemporary monitoring needs environmental, industrial, medical, homeland security applications. Here, we show three designs photonic nanostructured as In all designs, the first variable sensor response is optical wavelength across visible spectral range. The second either (i) illumination angle, (ii) light polarization, or (iii) operation temperature sensor. These illustrative bring mathematical understanding boost multi-gas resolution achieved by individual material-based through transducer, material design, appropriate excitation conditions, data analytics. Results presented this report should inspire new fundamental research technological innovations areas sensors, optics, materials science, nanofabrication, strategic approach expanding dimensionality described study will enable next generation perform on par orthogonal-output instruments, but a continuous real-time stream unobtrusive, energy-efficient designs.

Опубликована: Ноя. 5, 2024

Abstract The future of environmental monitoring, medical diagnostics, and industrial safety depends on developing room‐temperature, long‐term operable, stable, miniaturized, ultrahigh‐performance sensors integrated into the Internet Things (IoT). While noble metals high‐entropy alloys (HEAs) lead in addressing limitations conventional transition‐metal dichalcogenides (TMDs) like MoS₂, they face challenges such as high‐cost, limited availability, fabrication complexity. To address this, multifunctional, cost‐effective, humidity‐insensitive novel phase Ti₀.₅Zn₀.₅ (TiZn) alloy nanoparticle‐decorated MoS₂ nanosheets (MoS₂_NP) is developed for ultra‐selective highly sensitive triethylamine (TEA) vapor detection at room temperature (RT). This exhibited a 24‐fold increase response compared to with high signal‐to‐noise ratio, negligible humidity interference, sensitivity 9.92 × 10⁻⁵ ppm⁻¹ RT, limit 48 ppm. enhanced catalytic activity defect concentration, reduction edge oxidation resulting strong Fermi‐level pinning, relatively adsorption energy target gas‐specific carrier‐type response, demonstrating potential binary nanoparticles (NPs) decorative materials sensing applications. superior performance sensor led development TEA prototype interfaced mobile device via IoT continuous enhancing practicality usability by offering immediate access critical information.
