Multienzyme chemiluminescent foldable biosensor for on-site detection of acetylcholinesterase inhibitors

The rapid hydrolysis of acetylcholine (ACh), one of the key neurotransmitters in the human body, by the enzyme acetylcholinesterase (AChE) is fundamental for the termination of ACh impulse transmission. Several chemicals, including organophosphorus (OP) pesticides, warfare agents and drugs, are AChE reversible or irreversible inhibitors, thus their rapid on-site detection is of primary importance. Here we report for the first time a...
