  2. 1. Microfluidics in Surface Modified PDMS : Towards Miniaturized Diagnostic Tools

    Author : Sara Thorslund; Fredrik Nikolajeff; Jonas Bergquist; Elisabeth Verpoorte; Uppsala universitet; []
    Keywords : Materials science; µTAS; micro total analysis system; PDMS; poly dimethylsiloxane ; microfluidics; heparin; blood filtration; on-chip; ESI-MS; desalting; QCM-D; biocompatible; CD4; capillary flow; lab-on-chip; microfabrication; enrichment; point-of-care; hydrophilic; oxidation; Materialvetenskap;

    Abstract : There is a strong trend in fabricating miniaturized total analytical systems, µTAS, for various biochemical and cell biology applications. These miniaturized systems could e.g. gain better separation performances, be faster, consume less expensive reagents and be used for studies that are difficult to access in the macro world.

  5. 3. Immuno-affinity interactions in sample preparation and analysis

    Author : Madalina Tudorache; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; immuno supported liquid membrane ISLM extraction; sample preparation; immunoassay; immuno-affinity interaction; antibody; Analytical chemistry; Analytisk kemi;

    Abstract : Immuno-affinity interactions (antibody-antigen) belong, together with enzyme-inhibitor/substrate/coenzyme; oligosaccharide-lectin; DNA/RNA-protein interactions etc, to the class of bio-recognition. Immuno-affinity is widely used for analysis in immunoassays with numerous applications in a variety fields (i.e. READ MORE

  6. 4. Experimental Studies of Complex Flows through Image-Based Techniques

    Author : Gabriele Bellani; FredrIk Lundell; James Olsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Abstract : This thesis deals with the development of experimental techniques for the study of complex flows inspired to a large extent by the papermaking process. In particular one part of this thesis is devoted to the development of laboratory experiments based on index-of-refraction matching and imaging techniques to study the behavior of dilute and concentrated suspension of elongated particles.

  7. 5. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

    Author : Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

    Abstract : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. READ MORE
