  1. 1. New Methods for Enzyme Hydrolysis, Analysis, and Characterization of Modified Cellulose

    Författare :Claes Melander; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Methyl Cellulose; Reducing End; Micro Immobilised Enzyme Reactor; Mass Spectrometry; Enzyme Hydrolysis; Modified Cellulose; Substituent Distribution;

    Sammanfattning : Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties.

  3. 2. 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
