  1. 1. Droplet microfluidics for high throughput biological analysis

    Författare :Håkan Jönsson; Helene Andersson-Svahn; Andrew Griffiths; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microfluidics; Droplet microfluidics; High throughput biology; Single cell analysis; Hydrodynamic separation; Enzyme amplification; Fluorescence polarization; Microfabrication; Bioengineering; Bioteknik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : Many areas of biological research increasingly perform large-scale analyses.  In genomics the entire gene repertoire of an organism is analyzed.  Proteomics attempts to understand the function and expression patterns of all proteins in a cell or organism. LÄS MER

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

    Författare :Sara Thorslund; Fredrik Nikolajeff; Jonas Bergquist; Elisabeth Verpoorte; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Centrifugal microfluidics-based point of care diagnostics at resource limited settings

    Författare :Ahmad Saleem Akhtar; Aman Russom; Ines Fernandes Pinto; Nicole Pamme; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microfluidics; centrifugal microfluidics; point-of-care; low-cost; diagnostics; agarose beads; immunoassays; colorimetry; fluorescence; cytokines; nucleic acid amplification; isothermal amplification; COVID-19; portable; smartphone; resource limited settings.; Biotechnology; Bioteknologi;

    Sammanfattning : Advancements in medical diagnostics have allowed us to understand the underlying mechanism and treat the root cause for many diseases which had been causing morbidity and mortality up until this point in human history. Furthermore, many of the standard diagnostic procedures have now been transformed to provide answers at or near the point-of-care. LÄS MER

  5. 4. The application of microfluidic devices and multifunctional fibers in cancer diagnostics

    Författare :Tharagan Kumar; Aman Russom; Fredrik Laurell; Gustaf Mårtensson; Johan Kreuger; KTH; []
    Nyckelord :Circulating tumor cells; microfluidics; point of care; inertial microfluidics; elasto inertial microfluidics; nano-cellulose; layer-by-layer; optical fiber; microflow cytometer.; Bioteknologi; Biotechnology;

    Sammanfattning : Efficient separation and detection of rare cells in a mixed population is important in many biomedical applications. For instance, isolating and detecting circulating tumor cells (CTCs) from whole blood samples could allow for early cancer diagnosis and prognosis during treatment. LÄS MER

  7. 5. Microfluidics for High-Pressure Inertial Focusing : Focusing, Separation and Concentration of Micro and Sub-micron Particles

    Författare :Javier Cruz; Klas Hjort; Aman Russom; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microsystems; Microfluidics; Inertial Focusing; Particle Manipulation; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : The birth of microsystems set the ground for technologies never imagined before, for it is not only the small size what characterizes the miniaturized systems, but unique phenomena arise in the micro scale. This thesis relates to one such unique phenomenon, inertial focusing, a phenomenon that occurs in microfluidic systems if very special conditions are met and that allows for fine manipulation of particles in fluid samples.
