Determination of pesticide residues in food, water, and the environment is crucial for the well-being of human and animals. This is because organophosphates and carbamates, two groups of widely applied pesticides in the agriculture, could inhibit cholinesterase enzyme which then may cause pyrolysis and finally death (Perry et al., 1998) to the livings. The main aim of this work is, therefore,...

A sensor for detecting pesticide by the inhibition of acetylcholine esterase (AChE) enzyme have been fabricated by direct immobilization in an agarose matrix on the surface of ion-sensitive field-effect transistors (ISFET). The enzyme entrapment was achieved by mixing AChE (0.01U) in an agarose gel buffer solution, and droping the mixture onto the surface of ISFET. This AChE-ISFET sensor was...

An extended gate field-effect transistor (EGFET) is a device that can be applied to chemical sensing with the benefit of low cost electrodes. A poly(methylmethacrylate) (PMMA)-imprinted film has been applied to fabricate on indium tin oxide glass as a gate electrode for an EGFET sensor for a specific detection of carbaryl sample. The imprinted film was obtained by mixing PMMA and carbaryl in...

Organic field effect transistors (OFETs) are widely utilized in alternative disposable electronic devices. These devices provide fabrication simplicity, low-cost, fast, and adequate sensitivity. A water-gated OFETs have been reported to operate under low-voltage with low-energy consumption and applied to DNA sensor. In this study, Bottom-contact top-gate water-gated OFETs were fabricated....
