“…For this reason, NO 2 detection at sub-ppm concentrations is especially important for pollution control, and many types of gas-sensing systems have been developed for its detection, including electrochemical, optical and chemiresistive sensing. Among the various types of gas sensors, the metal oxide semiconductor (MOS) gas sensor shows high responsivity, fast response and recovery times and a vast choice of semiconductor metal oxides as gas-sensitive layers [2][3][4].…”

NO2 is an important environmental pollutant and is harmful to human health even at very low concentrations. In this paper, we propose a novel chipless RFID sensor able to work at room temperature and to detect sub-ppm concentration of NO2 in the environment. The sensor is made of a metallic resonator covered with NO2-sensitive tin oxide and works by monitoring both the frequency and the intensity of the output signal. The experimental measurements show a fast response (a few minutes) but a very slow recovery. The sensor could therefore be used for non-continuous threshold monitoring. However, we also demonstrated that the recovery can be strongly accelerated upon exposure to a UV source. This opens the way to the reuse of the sensor, which can be easily regenerated after prolonged exposure and recycled several times.

“…Several methods were used to measure NO, including Griess test [ 24 , 25 ], chemiluminescence [ 26 ], electron spin resonance (ESR) [ 27 , 28 ], fluorescent probe [ 29 , 30 ] and electrochemical sensing [ 31 , 32 ]. Apart from these, waveguide microwave sensors are also utilized for the detection of nitrogen oxides due to their simplicity, low cost, passive and non-contact operations [ 33 , 34 ]. The determination of NO in biological samples imposes a number of special requirements on sensor devices, such as low price, simple sample preparation, small size and a low detection limit of about 10 ppb.…”

Nitric oxide (NO) is a highly reactive toxic gas that forms as an intermediate compound during the oxidation of ammonia and is used for the manufacture of hydroxylamine in the chemical industry. Moreover, NO is a signaling molecule in many physiological and pathological processes in mammals, as well as a biomarker indicating the course of inflammatory processes in the respiratory tract. For this reason, the detection of NO both in the gas phase and in the aqueous media is an important task. This review analyzes the state of research over the past ten years in the field of applications of phthalocyanines, porphyrins and their hybrid materials as active layers of chemical sensors for the detection of NO, with a primary focus on chemiresistive and electrochemical ones. The first part of the review is devoted to the study of phthalocyanines and porphyrins, as well as their hybrids for the NO detection in aqueous solutions and biological media. The second part presents an analysis of works describing the latest achievements in the field of studied materials as active layers of sensors for the determination of gaseous NO. It is expected that this review will further increase the interest of researchers who are engaged in the current level of evaluation and selection of modern materials for use in the chemical sensing of nitric oxide.
