Methylphosphonic acid (MPA) is the degradation product of many chemical warfare agents. The convenient detection of this substance would aid in field testing to confirm illicit manufacture and use of banned chemical weapons. Efficient functionalization of MPA with an aromatic diazo compound allowed binding by monoclonal antibodies elicited by using an analogous hapten (see scheme). An ELISA assay was rapid, sensitive, and specific.

We have assessed the human liver microsomal (HLM) metabolism of the chemical warfare nerve agents' sarin (GB), cyclosarin (GF), and the Novichok agents A-230 and A-232. In HLM, GB showed drastically decreased stability ( = 1.4 h).

Organophosphorus nerve agents (OPNAs) are highly lethal chemical warfare agents (CWAs), which poses a serious threat to human health and safety. The accurate and rapid identification of OPNAs is crucial for medical diagnosis and effective treatment. However, distinguishing between various OPNAs and their analogues using on-site point-of-care testing (POCT) remains challenging.

Sulfur mustard (SM) is a chemical warfare agent that increases oxidative stress in veterans. The literature assessing oxidant/antioxidant parameters in SM-exposed veterans contains conflicting results. A total of 11 relevant studies were identified and screened.

Purpose: Sulfur mustard gas (SM) exposure to eyes causes multiple corneal injuries including stromal cell loss in vivo. However, mechanisms mediating stromal cell loss/death remains elusive. This study sought to test the novel hypothesis that SM-induced toxicity to human corneal stromal fibroblasts involves ferroptosis mechanism via p38 MAPK signaling.

We report the exfoliation of ultrathin gallium oxide (GaO) films from liquid metal balloons, formed by injecting air into droplets of eutectic gallium-indium alloy (eGaIn). These GaO films enable the selective adsorption of carbon nanotubes (CNTs) dispersed in water, resulting in the formation of a dense, percolating CNT network on their surface. The self-assembled CNT network on GaO provides a versatile platform for device fabrication.
