An Extended-gate Type Organic FET Based Biosensor for Detecting Biogenic Amines in Aqueous Solution.

چکیده
This study is the first to report on the detection of biogenic amines in an aqueous solution using an organic field-effect transistor (OFET) device with an extended gate electrode modified with a layer of diamine oxidase and a horseradish peroxidase osmium-redox polymer. The limit of detection (LOD) for histamine was estimated to be 1.2 μM. These results reveal that extended-gate type OFET devices are highly suitable enzyme-based biosensors for the detection of biogenic amine levels.

متن کاملExtended-Gate Field-Effect Transistor based Sensor for Detection of Hyoscine N-Butyl Bromide in its Pharmaceutical Formulation
A novel recognition method for selective determination of the hyoscine N-Butyl bromide (HBB), an antispasmodic agent for smooth muscles, was devised using extended gate field-effect transistor (EG-FET) as transducing unit. For this purpose a PVC membrane, containing hyoscine n-butyl-tetraphenyl borate ion-pair as recognition component, was coated on Ag/AgCl wire, which was connected to the exte...
متن کاملDNA detection by an extended-gate FET sensor with a high-frequency voltage superimposed onto a reference electrode.
An extended-gate field-effect-transistor (FET) sensor with a gold-sensing electrode, to which a gold-thiol bond could easily be applied, was developed for DNA detection. Because the gold electrode is located in a different area from the FET, it can be operated without a light-shielding box by masking only the FET. However, when the FET sensor is used in an aqueous solution, fluctuation of the i...

The fabrication and measurements of solution-processed vertically stacked complementary organic field-effect transistors (FETs) with a high static noise margin (SNM) are reported. In the device structure, a bottom-gate p-type organic FET (PFET) is vertically integrated on a top-gate n-type organic FET (NFET) with the gate shared in-between. A new strategy has been proposed to maximize the SNM b...
