“…The environmental quality of air is categorized into four levels as follows in terms of ozone such as excellent level means the ppb ranges from 0-50; good level means 50-100 ppb; poor level means 100-200 ppb and very poor means greater than 210 ppb (Mahmoud et al 2023;Hertig et al 2023). The level of noise in the background naturally is 30ppb (Zheng et al 2023). Thus, it is quite important to tracking the level of ozone gas in the air because, it poses a concern to public health and the environment, since they can harm the respiratory system, causing a loss in lung function, inflammation of the airways, and discomfort (Breitner-Busch et al 2023;Boshoman et al 2023).…”

<p>Ozone depletion arises due to the presence of gases like chlorofluorocarbons and halons which are liberated into the atmosphere. The region of earth’s atmosphere named as ozone shield, in which absorbs the ultra violet radiations of the sun. Although, its thickness varies periodically, this layer is primarily located in the lower stratosphere between 15 to 35 kms above the earth. Due to this, the ultraviolet rays directly enter into the earth causes harmful effects little by little on both living and non-living organisms. In this paper, BIn2O3 with rh sensor in co precipitation method is used to detect the ozone depletion and it is based on the solid-state gas sensors. To achieve the excellent performance of an ozone depletion detecting branch like BIn2O3 with rh, this was designed using a simple precipitation method. The coprecipitation method had deposited in BIn2O3 with a thickness of 45 to 50 nanometer. The detection limit of ozone reduced as 30 parts per billion. Further, the gas detector demonstrated high sensitivity and selectivity of the device. The rhodium covers the surface areas ranges from 0 to 0.1. It reaches the accuracy of 96%. According to the degree of rhodium coverage, the sensors will be response to the ozone gas. The oxygen chemisorbed ability and a coverage of a great surface area of BIn2O3 with rhodium highly related to the excellent sensing behavior. This study paves the way for an exact sensing and ppb level detection ozone gas.</p>

“…Many fluorescent probes have recently been designed to monitor HOCl based on different recognition receptors [ 25 , 26 , 27 , 28 ]. Fluorescent probes have some unique advantages in many respects, and still, many lack the abilities for biological applications, e.g., low sensitivity, poor selectivity, and limited applications during in vivo bioimaging [ 29 , 30 , 31 , 32 , 33 ]. A major challenge in monitoring HOCl is that its precise roles in biological activities remain elusive.…”

Hypochlorous acid (HOCl) has been implicated in numerous pathologies associated with an inflammatory component, but its selective and sensitive detection in biological settings remains a challenge. In this report, imaging of HOCl was realized with a thiomorpholine-based probe as derivative of nitrobenzothiadiazole (NBD-S-TM). The fluorescence is based on photoinduced electron transfer by using nitrobenzothiadiazole core as a donor and thiomorpholine substituent as an acceptor. NBD-S-TM showed high sensitivity and a fast response to HOCl k = (2.6 ± 0.2) × 107 M−1s−1 with a 1:1 stoichiometry. The detection limit for HOCl was determined to be 60 nM. Furthermore, the desirable features of NBD-S-TM for the detection of HOCl in aqueous solutions, such as its reliability at physiological pH, rapid fluorescence response, and biocompatibility, enabled its application in the detection of HOCl in myeloperoxidase enzymatic system. Moreover, NBD-S-TM exhibited excellent selectivity and sensitivity for HOCl over other biologically relevant species, such as hydrogen peroxide and peroxynitrite. The fluorescent S-oxidized product (NBD-S-TSO) is only formed in the presence of HOCl. Probing with NBD-S-TM may be helpful to further the development of high throughput screening assays to monitor the activity of myeloperoxidase.
