  4. 3. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules

    Författare :Mats Jönsson; Ulf Lindberg; Bertil Hök; Johan Nilsson; Uppsala universitet; []
    Nyckelord :Engineering physics; sensor; micro; dielectrophoresis; impedance; electrode; beads; cell; flow; bacteria; microfabrication; biosensor; electrocapture; microfluidic; planar; Lab on chip; µTAS; micro total analysis system; QCM; dispersion; field-flow fractionation; ITO; design; fabrication; Teknisk fysik;

    Sammanfattning : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept. Microfluidic devices tend to become increasingly complex in order to include, e.g. LÄS MER

  5. 4. Interaction of flows with slender structures and liquid-infused surfaces

    Författare :Johan Sundin; Shervin Bagheri; Daniel Chung; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow-structure interactions; flow control; turbulent boundary layers; soft sensors; drag reduction; capillary waves; surfactants; Marangoni stress; mixing enhancement; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Surface textures and protrusions can be used to control or gain information about a flow. We investigate the solid-flow interaction of filamentous structures and liquid-infused surfaces (LIS). Both filamentous structures and LIS are used by organisms and can be exploited in technical applications. LÄS MER
