  1. 1. Heterogeneous Technologies for Microfluidic Systems

    Författare :Gunjana Sharma; Klas Hjort; Sami Franssila; Uppsala universitet; []
    Nyckelord :actuator; biosensor; fluidic circuit board; heterogeneous technology; ion track; microfluidic; pump; stainless steel; super-hydrophobic; valve; Viton; TECHNOLOGY; TEKNIKVETENSKAP; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : In this thesis, conventional and unconventional technologies have been studied and combined in order to make heterogeneous microfluidics with potential advantages, especially in biological applications. Many conventional materials, like silicon, glass, thermoplastic polymers, polyimide and polydimethylsiloxane (PDMS) have been combined in building heterogeneous microfluidic devices or demonstrators.

  3. 2. Microfluidic biosensing systems based on enzymes, antibodies and cells

    Författare :Richard Davidsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; chemiluminescence; immobilization; cell; antibody; enzyme; miniaturization; Microfluidic; microchip;

    Sammanfattning : The rapid developments within the life science and biotechnology areas put up ever-new demands on more sophisticated techniques and methods for chemical and biological analysis to reach deeper insight into the events at molecular level. Miniaturisation of assays and systems on microchips is one way to increase throughput and advance through parallel analysis lines, multiplexing and integration. LÄS MER

  4. 3. Paraffin Actuators in Microfluidic Systems

    Författare :Marcus Lehto; Klas Hjort; Peter Woias; Uppsala universitet; []
    Nyckelord :Engineering physics; Paraffin; Actuators; Valve; Micropump; Teknisk fysik;

    Sammanfattning : There is a need for reliable valves and pumps in microfluidics. A good microactuator is the key for low cost and high performance of these components.Paraffin wax is a promising material to be used as actuator material as is can produce large forces and large strokes. LÄS MER

  5. 4. Thermoplasmonic Effects in Microfluidic Systems

    Författare :Steven Jones; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermometry; thermoplasmonic bubbles; thermoplasmonics; plasmonics; thermophoresis;

    Sammanfattning : The field of plasmonics has enabled a plethora of scientific achievements over the past few decades. Such advances have been the result of the increased light-matter interaction that occurs over nanoscale dimensions facilitated by the localized plasmonic resonances supported by noble metal nanoparticles.

  7. 5. Optical manipulation and spectroscopy of single functional globin-containing cells in microfluidic systems

    Författare :Kerstin Ramser; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heme-proteins; optical manipulation; resonance Raman spectroscopy; microfluidic systems; single cells; Medical Engineering for Healthcare;

    Sammanfattning : Recent advances in microbiology and biomedicine require development of tools to monitor the response of single cells to environmental stimuli under controlled physiological conditions. In this thesis, I describe how this can be achieved by combining various spectroscopic techniques with optical tweezers and microfluidic systems. LÄS MER
