  5. 3. Amperometric Carbon Paste Biosensors Based on Horseradish Peroxidase and Oxidases

    Author : Vijayakumar Rajendran; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; on-line monitoring; l-lactate; glucose; ethanol; Biosensor; Carbon paste; Analytisk kemi;

    Abstract : Amperometric carbon paste peroxide sensors based on horseradish peroxidase (HRP) were developed. In the first approach, HRP was chemically modified with polyethylene glycol to improve the stability of the enzyme in the organic paste matrix and compared with native HRP electrode. READ MORE
