  2. 1. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection

    Author : Niklas Larsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microdialysis; Liquid chromatography; Flow injection; Polyelectrolytes; Carbohydrate; Mediator; Dehydrogenase; Peroxidase; Oxidase; Enzyme; Amperometric detection; Carbon paste; Biosensor; Graphite electrode; On-line monitoring; Analytical chemistry; Analytisk kemi;

    Abstract : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. READ MORE

  4. 2. 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

  5. 3. Sensor Systems for Bioprocess Monitoring

    Author : Helena Lidén; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

    Abstract : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. READ MORE
