“…However, their high-power consumption hinders their utilization in battery-driven devices. Several detection techniques including surface plasmon resonance, surface acoustic wave, fluorescent and colorimetric sensing technologies have been used to develop highly sensitive and selective CO 2 gas sensors that can operate at ambient temperatures [ 44 ]. However, there are still many challenges that restrict the commercial availability of these sensing devices including high complexity of the structural configuration, its large size and high cost [ 44 ].…”

However, there are still many challenges that restrict the commercial availability of these sensing devices including high complexity of the structural configuration, its large size and high cost [ 44 ]. Recently, hollow nanostructures have attracted much attention as promising nano-designed gas sensors due to their unique porous morphology, high specific surface area and effective gas diffusion [ 45 , 46 , 47 ].…”

In the last decades, nanomaterials have emerged as multifunctional building blocks for the development of next generation sensing technologies for a wide range of industrial sectors including the food industry, environment monitoring, public security, and agricultural production. The use of advanced nanosensing technologies, particularly nanostructured metal-oxide gas sensors, is a promising technique for monitoring low concentrations of gases in complex gas mixtures. However, their poor conductivity and lack of selectivity at room temperature are key barriers to their practical implementation in real world applications. Here, we provide a review of the fundamental mechanisms that have been successfully implemented for reducing the operating temperature of nanostructured materials for low and room temperature gas sensing. The latest advances in the design of efficient architecture for the fabrication of highly performing nanostructured gas sensing technologies for environmental and health monitoring is reviewed in detail. This review is concluded by summarizing achievements and standing challenges with the aim to provide directions for future research in the design and development of low and room temperature nanostructured gas sensing technologies.

“…Їх використовують для вимірювання наявності чи концентрації газів у повітрі, а також йонів або окремих продуктів життєдіяльності організму в біологічних рідинах [9]. Гнучкі сенсори газів зазвичай є гнучким резистивним елементом, який виявляє залежність опору до концентрації певного газу в довкіллі [53][54][55][56][57][58][59][60][61]. Нині створено низку гнучких газових сенсорів, здатних реєструвати з достатньою чутливістю водень, вуглекислий газ, чадний газ, оксиди азоту, сірководень й аміак (табл.…”

Background. Currently, there is a significant number of technologies and materials in the world that are used to manufacture flexible electronics devices. Therefore, a review of various technologies and materials for the manufacture of flexible sensors, which would not be inferior in terms of sensitivity to their solid-state counterparts, is in demand. In addition, most modern flexible electronics technologies are based on the use of artificial polymers, the production of which pollutes the environment and which need to be disposed of at the end of its service life. Therefore, there is an urgent need to find an alternative to artificial polymers, environmentally friendly material. Objective. The purpose of the paper is to determine design and technological features of manufacturing and application of flexible and biodegradable electronic sensors. Methods. The article analyses, classifies and compares different technologies and materials for the manufacture of flexible sensors, which would not be inferior to their solid-state counterparts in terms of sensitivity. The technological features of synthesis and the main characteristics of flexible sensors made on the basis of artificial and biodegradable materials were also compared in the paper. Results. The design and technological features of manufacturing as well as application of flexible electronic sensors in comparison with their solid-state analogues were determined in the paper. Three groups of substrate materials that can be used for the synthesis of flexible sensors have been identified and their performance characteristics analysed. A comparison of different production techniques for flexible electronic sensors in terms of environmental friendliness, cost and manufacturability is carried out. Conclusions. The most promising biodegradable material, on the surface of which one can create a flexible sensor, is nanocellulose. Different types of printing are the most promising production technique for the manufacture of such devices, because they are cheap and can provide high productivity. Based on the obtained results, it is possible to improve the existing and develop new methods of creating flexible electronics devices that do not require recycling.

“…Long term exposures can lead to brain damage, heart dysfunction, breathing difficulties and muscle weakness. When inhaled it combines with Gas sensors [81] hemoglobin in the blood by displacing oxygen and forming carboxyhemoglobin which causes the cell and organs to become hypoxic (lacking of oxygen). The brain and heart consumes large amount of oxygen but due to the toxicity of carbon monoxide the brain and heart cells will lack adequate oxygen for proper functioning [81].…”

Environment pollutants are found here and there in developing countries and these contaminations affect the environment adversely. A few remediation of pollution which includes incineration which is the waste treatment process that involves the combustion of organic substances contained in waste material, the waste handling practices, the recycling resource recovery, the avoidance and reduction methods, the adsorption based on nanotechnology and the bioremediation technology which appears as a cost-effective and environmental friendly approach for cleanup. Recently researches shows that various chemicals (VOCs, BTEX, heavy metals) that might be delivered into the air or water can cause unfriendly health effects which was analyzed based on sample treatments (solid phase extraction: SPE, the liquid-liquid microextraction: LLME, the magnetic solid phase extraction: MSPE) and instruments such as ET-AAS, F-AAS and GC-FID methods. The related weight of disease can be substantial, and interest in research on health effects and intervention in explicit populations and openness circumstances is significant for the development of control systems. Pollution control and determination is thusly a significant segment of disease control, and health experts and analytical chemistry specialists need to foster associations with different areas to recognize and carry out need interventions.
