“…polymers) ( Adhikari and Majumdar, 2004 ) that do not require heating elements or complex fabrication steps (this is the case for MOS sensors) and are therefore cost-effective and easily integrated with inorganic materials such as metallic Nanoparticles (NPs) so as to obtain devices with improved properties. Cross-linked Au NPs in particular have been used in order to prepare chemiresistors capable of detecting various environmental pollutants as well as VOCs for the detection of breath biomarkers for disease detection ( Carvalho et al, 2017 , Zhao et al, 2016 ). Limited results have been reported up to now for pesticide gas-sensors; dimethyl-methylphosphonate (DMMP, lab simulant of the toxic agent of sarin) has been successfully detected with a limit of detection (LOD) in the ppm range, using complex single-use sensors ( Yu et al, 2015 ); Organophosphate vapour sensing via Peptide nanotube biosensors with a short life span (45 days) and a LOD in the ppb regime has been reported ( Baker et al, 2014 ); a SnO 2 organophosphorus gas sensor operating at 250–300 ◦C, with a LOD of 1.053 μg/L has been also discussed ( Huang et al, 2004 ); Finally a nanopore sensor (agarose gel-based chip) has been used for the detection of vaporized omethoate (LOD of 100 ppb) through the complex formation with a DNA aptamer, and its obstruction at the nanopore ( Fujii et al, 2017 ).…”

Highlights A hybrid nanomaterial based gas-sensing array has been used for pesticide detection. The pesticide is the commercially available organophosphate based Chloract 48 EC. The array has successfully distinguished between relative humidity and pesticide. The successful operation of the array has been validated via the PCA method. This study expands the limited available results related to pesticide gas-sensors.

Micro- and nano-sensors lie at the heart of critical innovation in fields ranging from medical to environmental sciences. In recent years, there has been a significant improvement in sensor design along with the advances in micro- and nano-fabrication technology and the use of newly designed materials, leading to the development of high-performance gas sensors. Advanced micro- and nano-fabrication technology enables miniaturization of these sensors into micro-sized gas sensor arrays while maintaining the sensing performance. These capabilities facilitate the development of miniaturized integrated gas sensor arrays that enhance both sensor sensitivity and selectivity towards various analytes. In the past, several micro- and nano-gas sensors have been proposed and investigated where each type of sensor exhibits various advantages and limitations in sensing resolution, operating power, response, and recovery time. This paper presents an overview of the recent progress made in a wide range of gas-sensing technology. The sensing functionalizing materials, the advanced micro-machining fabrication methods, as well as their constraints on the sensor design, are discussed. The sensors’ working mechanisms and their structures and configurations are reviewed. Finally, the future development outlook and the potential applications made feasible by each category of the sensors are discussed.

The applications of functional polymers to different research fields have been increasing. An especially important application is the use of polymer‐based sensors for the chromogenic detection of compounds of environmental interest in water. Polymer matrix supports have been developed to improve the sensing capacity and performance of chromogenic sensors. Therefore, research in the area of sensor design and manufacturing for pollutant detection is increasingly interesting to many scientific communities ranging from biological and chemical sciences to engineering. This subject of this review is colorimetric sensors that enable the rapid and quantitative detection of different analytes within a laboratory setup. The applications of different types of polymer‐based sensors used in the chromogenic detection of compounds of environmental interest are reviewed and analysed. © 2021 Society of Industrial Chemistry.
