  4. 3. Porous Silicon -an enzyme coupling matrix for micromachined reactors

    Författare :Johan Drott; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; glucose; biosensor; immobilised enzyme; porous silicon; microreactor; Mät- och instrumenteringsteknik;

    Sammanfattning : The development of a miniaturised silicon wafer integrated enzyme reactor is described. The reactor was micromachined by anisotropic wet etching of (110) silicon. The enzyme glucose oxidase (GOx) was coupled to the reactor surface with standard methods of immobilising enzyme to silica. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
