Paraoxon is a parasympathomimetic which acts as an acetylcholinesterase inhibitor. It is an organophosphate oxon, and the active metabolite of the insecticide parathion. It is also used as an ophthalmological drug against glaucoma. Paraoxon is one of the most potent acetylcholinesterase-inhibiting insecticides available, around 70% as potent as the nerve agent sarin, and so is now rarely used as an insecticide due to the risk of poisoning to humans and other animals. Paraoxon has been used by scientists to study acute and chronic effects of organophosphate intoxication. It is easily absorbed through skin, and was used as an assassination weapon by the apartheid-era South African chemical weapons program Project Coast.
Nanocomposite and preparation method, nanoscale enzyme-bioenzyme cascade sensor and application
PendingCN122252263AMaterial nanotechnologyMaterial analysis by observing effect on chemical indicatorMicron scaleNanocomposite
This invention discloses a nanocomposite material and its preparation method, a nanoenzyme-bioenzyme cascade sensor and its application, relating to the field of pesticide detection technology. The technical solution of this invention introduces flexible two-dimensional graphitic carbon nitride nanosheets as a soft template and spatial confinement agent for in-situ growth, effectively suppressing the excessive growth of PCN-222(Fe) crystals during the solvothermal process, successfully controlling its size from the micrometer scale to the submicrometer scale, resulting in higher catalytic activity. The nanoenzyme-bioenzyme cascade sensor constructed based on this composite material achieves broad-spectrum, ultrasensitive detection of pesticides such as glyphosate, dimethoate, and paraoxon. This sensor has a low detection limit in the pM-nM range, a wide linear range, and exhibits excellent recovery and precision in complex real-world samples, strong anti-interference ability, and high practicality.
