Mononitrotoluenes (MNTs) can cause methemoglobinemia, liver/kidney damage, and skin/eye/throat irritation. Monitoring of MNTs in real and laboratory samples is necessary to maintain levels below permissible limits. Herein, silver oxide quantum dots (Ag2O QDs) were synthesized using a chemical method and were well characterized using transmission el...

... NPs have a high surface-to-volume ratio that enables enhanced contact with the target organisms [7][8][9][10][11]. NPs can also interact with bacterial cells to regulate the uptake and molecular pathways [12][13][14]. In particular, gold nanoparticles (AuNPs) exhibit additional attributes to help in this endeavor, including chemical stability, biocompatibility, commercial availability, easy functionalization, and high intrinsic antimicrobial activity [15][16][17][18][19]. AuNPs also possess remarkable optical properties related to plasmon absorption, which allow their use in photothermal-induced antibacterial therapy [20,21]. ...
... Recently most interesting materials for gas sensing and electrochemical sensing/ biosensing applications include the metal oxides [17][18][19], bio-inspired graphene [20], MXenes [21], metal complexes of pyridylchalcogens [22], etc. The exceptional physical and chemical features of metal oxides have given them substantial popularity and useful application in semiconductor industries over time. ...
... Due to the high surface-to-volume ratio, greater oxidant capacity and bio persistence, nanoparticles became the primary source for toxicity, which can penetrate easily through epithelium and reach to interstitial pulmonary area. There are real needs to protect our public and environmental health and safety, specially where the standards or guidelines that can directly rule nano materials effects are not exist in present time [11]. However, the tunable and varied physicochemical properties of Nanoparticles pose a new challenge for understanding their biological behavior, and bio distribution, so the in vivo and in vitro kinetics can be controlled to meet the requirements of efficient drug delivery and minimizing side-effects. ...

... In the last two decades, many researches focused on the development of OCPs-based electrochemical sensors for the detection of heavy metal ions in waters. Indeed, OCPs are an important class of materials that combine the physicochemical properties of both organic polymers (such as strength, plasticity, flexibility, toughness, elasticity) and semiconductors (e.g., electric conductivity) [7]. They are relatively easy to manufacture, corrosion resistant, nonpolluting, and highly sensitive for detection and even very effective for metal removal [8][9][10]. ...
... Among these methods, electrochemical analysis finds significant application for determination of NACs due to their cost effectiveness, ease of operation, lesser time consumption, high selectivity, and sensitivity (Chakraborty et al., 2021;Madhu et al., 2014). To have better analytical performance, different materials like hydrogel based (Puttasakul et al., 2019), molecular imprinted polymers (MIPs) (Nie et al., 2011), aptamer-based materials (Ho et al., 2012), metal (Singh et al., 2016) and metal oxide (Bhanjana et al., 2019a) based nanomaterials have been exercised for fabrication of modified sensors to detect nitrotoluenes. Metal oxide-based NPs such as silver oxide (Ag 2 O) (Rahman et al., 2012b), zinc oxide (ZnO) (Solanki et al., 2009), copper oxide (CuO) (Bhanjana et al., 2019c), manganese oxide (Mn 3 O 4 ) (Bhanjana et al., 2019b), have found significant applications for sensing of organic pollutants due to their semiconducting nature as well as excellent electrocatalytic properties. ...
