Chemical warfare agents (CWAs) have been listed as lethal weapons of mass destruction due to their extreme toxicity and devastating effects. Detection and detoxification are essential to protect ourselves from such acutely perilous agents and have therefore generated a great deal of research interest. In this context, studies show that adsorbents such as activated carbon, metal oxides, and metal organic frameworks (MOFs) are active materials for the effective degradation of CWAs. Among them, MOFs are preferred because of their large surface area, tunable porosity, and catalytic, functional, and chemical stability properties. With this background, we comprehensively review the historical purview of the utility of CWAs, the potency of various CWAs, and their toxic profiles. Further, we discuss the research strategies reported to synthesize MOFs of desirable characteristics by tuning the synthesis parameters such as solvents, temperature, guest molecules, and organic ligands. Specifically, we highlight the multifarious studies of the impregnation of MOFs onto fibers/textiles as selfprotecting fabrics using different techniques. Finally, we enumerate the challenges in developing MOFs-incorporated textiles and their functionalization toward the detection and detoxification of CWAs. As a future perspective, further requirements and possibilities of using MOF-modified textiles as wearable electronic devices for the detection and detoxification of CWAs have also been addressed.

4-Nitrophenol (4-NP) is a hazardous organic pollutant with detrimental effects on plants, animals, and humans. Detection of 4-NP in the environment is therefore a necessary requirement. We demonstrate a facile green synthesis of nickel-oxide (NiO) nanoparticles employing Brassica oleracea vegetable extract (cauliflower) as a green stabilizing and reducing agent. Green synthesized NiO nanoparticles were used as an efficient electrode material for the highly sensitive electrochemical detection of 4-NP. The abundant polyphenolic component in the vegetable extract of Brassica oleracea is capable of reducing and stabilizing C 2 NiO 4 into NiO nanoparticles. The as-synthesized NiO nanoparticles were characterized by UV-Vis spectroscopy, FTIR spectroscopy, Raman spectroscopy, photolumines-cence spectroscopy, and X-ray photoelectron spectroscopy (XPS), and the structural phase of NiO nanoparticles was confirmed using powder X-ray diffraction technique. The surface morphology of the NiO nanoparticles was analyzed using scanning electron microscopy (SEM). Linear sweep voltammetry (LSV) and Differential pulse voltammetry (DPV) techniques were adopted to for the electrochemical determination of 4-NP after drop casting the NiO nanoparticles onto the screen-printed carbon electrode (SPCE). The developed sensor (NiO/SPCE) showed a high sensitivity of 1.055 μA/nM over a wide linearrange from 1 to 10 nM with a detection limit of 0.519 nM for the detection of 4-NP using DPV technique.
