The smart, rapid, and customizable detection of chemical warfare agents is a huge issue for taking the proper countermeasures in timely fashion. printing techniques have established main pillar to develop miniaturized electrochemical biosensors onsite fast nerve mustard agents, allowing lab on chip agent sector. In growth novel technologies, combination with flexible electronics allowed deliver...

Organophosphorus (OP) nerve agents are potent toxins that inhibit cholinesterases and produce a rapid and lethal cholinergic crisis. Development of protein-based therapeutics is being pursued with the goal of preventing nerve agent toxicity and protecting against the long-term side effects of these agents. The drug-metabolizing enzyme human carboxylesterase 1 (hCE1) is a candidate protein-based...

Bacterial enzymes have been isolated that catalyze the hydrolysis of organophosphate nerve agents with high-rate enhancements and broad substrate specificity. Mutant forms of these enzymes have been constructed through rational redesign of the active-site binding pockets and random mutagenesis to create protein variants that are optimized for the detoxification of agricultural insecticides and ...

Organophosphorus (OP) compounds are organic derivatives of phosphorus that have largely been used as pesticides and nerve agents. Tetraethylpyrophosphate was synthesized in 1854 as the first OP cholinesterase inhibitor. During 1934–1944, Gerhard Schrader, a German chemist at I. G. Farben industries and his coworkers synthesized about 2,000 OP compounds, including parathion as a pesticide and ta...

The minimally-invasive nature of sclerotherapy makes it one of the first treatment options for venous malformations, although treatment-related complications, such as peripheral nerve paralysis, have been reported in some clinical cases. However, no studies of the aetiology of the detrimental effects of intraluminally-administered sclerotic agents on the surrounding tissues, including the perip...

An enzyme electrode for the detection of V-type nerve agents, VX (O-ethyl-S-2-diisopropylaminoethyl methylphosphonothioate) and R-VX (O-isobutyl-S-2-diethylaminoethyl methylphosphonothioate), is proposed. The principle of the new biosensor is based on the enzyme-catalyzed hydrolysis of the nerve agents and amperometric detection of the thiol-containing hydrolysis products at carbon nanotube-mod...

Nerve agents that irreversibly deactivate the enzyme acetylcholinesterase are extremely toxic weapons of mass destruction. Thus, developing methods to detect these lethal is important. To create an optical sensor for a surrogate nerve agent tabun, as well physical barrier dissolves in response this analyte, we devise network hydrogel decomposes via self-propagating cascade. A Meldrums acid-deri...
