Acetylcholinesterase based chronoamperometric biosensor for fast and reliable assay of nerve agents
Original language description
The enzyme acetylcholinesterase (AChE) is an important part of cholinergic nervous system, where it stops neurotransmission by hydrolysis of the neurotransmitter acetylcholine. It is sensitive to inhibition by organophosphate and carbamate insecticides,some Alzheimer disease drugs, secondary metabolites such as aflatoxins and nerve agents used in chemical warfare. When immobilized on a sensor (physico-chemical transducer), it can be used for assay of these inhibitors. In the experiments described herein, an AChE- based electrochemical biosensor using screen printed electrode systems was prepared. The biosensor was used for assay of nerve agents such as sarin, soman, tabun and VX. The limits of detection achieved in a measuring protocol lasting ten minutes were 7.41 x 10-12 mol/L for sarin, 6.31 x 10-12 mol /L for soman, 6.17 x 10-11 mol/L for tabun, and 2.19 x 10-11 mol/L for VX, respectively. The assay was reliable, with minor interferences caused by the organic solvents ethanol, met
