Abstract
A biosensor based on the principle of enzyme inactivation was used to detect some organophosphate OP pesticides in water samples. The system is composed of a nitrocellose paper membrane was physically attached to the sensitive ends of glass of pH electrodes. AchE-AcetylCholinesterase enzyme was used to immobilize to thee nitrocellulose paper membrane which tightly bound to the surface of the electrode. The enzyme acts as a transducer for this biosensor system. The output was measured as a voltage and the signal was transmitted to our own design interface card which link to the computer. Some experimental results have drawn from this work are discussed.
