  2. 1. Porous Silicon Microbioreactors - Applications and Technology

    Author : Martin Bengtsson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; immobilised cells; enzyme reactor; micro fluidics; Microreactor; porous silicon;

    Abstract : Microfluidic systems have become one of the most interesting fields in the research of chemical analysis. Miniaturized systems exhibit numerous practical advantages when compared with traditional batch-scale synthesis such as lower sample volumes, increased control of the reactions and higher sample throughput.

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

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

    Abstract : 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. READ MORE

    Abstract : The research work that I describe in my thesis deals with three different heterogenisation approaches for synthesising a heterogeneous transition metal catalyst used for direct C-H activation reactions. The three heterogenisation approaches considered in my research are: (1) heterogenisation of a molecular catalyst on a polymer support using covalent bonds, (2) heterogenisation of a catalyst on a reduced graphene oxide (rGO) support using non-covalent interactions and (3) immobilisation of a catalyst on an inorganic surface using covalent bonds and encapsulation in an inorganic matrix.
