生化战剂传感器最新进展ppt课件

1、研讨阐明，动物体中神经激动的传送物质是乙酰胆碱Ach，神经激动在传送时上一次激动释放出来的Ach会迅速的被乙酰胆碱酯酶AchE所水解，使得神经突触间或神经肌肉接头处的Ach的浓度下降，从而完成一个神经激动。然而有些有机物会与乙酰胆碱酯酶AchE首先发生作用，这样就抑制了AchE的活性，使之不能正常水解Ach，呵斥Ach的积累使神经传送受阻而产生中毒病症。被分析物生物敏感膜生物学反响信息换 能 器电信号二 次 仪 表(CH3)3N+CH2OCOCH3 + CH 3Cl-HCH3CCOPOH3CF酶HCH3CCOPOH3COCH2N+(CH3)3H3C+ HF + CH3COO-v其中 =W.Co
