Amperometric biosensor for formic acid in air

Amperometric biosensor for ascorbic acid

A L-ascorbic acid biosensor based on ascorbate oxidase has been developed. The enzyme was extracted from the mesocarp of cucumber (Cucumis sativus) by using 0.05 mol L phosphate buffer, pH 5.8 containing 0.5 mol L NaCl. After the dialysis versus phosphate buffer 0.05 mol L pH 5.8, the enzyme was immobilized onto nylon net through glutaraldehyde covalent bond. The membrane was coupled to an O 2 ...

Ascorbic Acid Determination by an Amperometric Ascorbate Oxidase-based Biosensor

The aim of this work is to develop a method for ascorbic acid determination in some fruit juices, by using an ascorbate oxidase-based amperometric enzyme electrode. The enzyme was immobilized on a nylon (Biodyne A) membrane by glutaraldehyde linking. The enzyme-membrane was consecutively attached to the polyethylene membrane of a Clark oxygen electrode, which functioned as transducer. The analy...

Characterization of Amperometric Biosensor in Cyclic Voltametry

In this paper, I would like to present basic characterization of Electro Chemical Biosensor. Biosensors are versatile , they are Amperometric and Immuno biosensors. In this paper the cyclic voltametry technique is used to detect the pathogens in analyte. The resultant graph is between voltage and current.The amperometric biosensor gives current as output which judges the pathogen present in ana...
