Application of light-addressable potentiometric sensor in organophosphorus insecticide determination

XU Lei, HAN Jinghong, LIANG Weiguo,ZHANG HongElectronics,Chinese Academy of Sciences,Beijing 100080,China)  
Lightaddressable potentiometric sensor (LAPS) can be used to determine organophosphorus insecticides by immobilizing acetyl cholinesterase (AchE) on its Si3N4 film (H+ selective).The operating principle and the way of preparation of the sensor are introduced ,and the influence of Tris buffer and acetylcholine substrate is also analyzed. Moreover the response characteristics under various inhibition time and various organophosphorus concentration are discussed. As a new approach to determine insecticides, this method has the advantages of simple operation,high sensibility and high efficiency.
