  1. 11. 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

  3. 12. Acoustic manipulation of cells and microbeads in droplet microfluidics

    Författare :Anna Fornell; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Droplet microfluidics; Enrichment; Lab-on-a-chip; Particle manipulation; Ultrasound;

    Sammanfattning : Droplet microfluidics has emerged as a promising platform for miniaturisation of biological assays on-chip. In droplet microfluidics small water droplets (nL-pL) surrounded by an immiscible carrier oil are generated at high throughput. LÄS MER

  5. 14. Tagging systems for sequencing large cohorts

    Författare :Mårten Neiman; Afshin Ahmadian; Peter Savolainen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; next generation sequencing; genotyping; massive parallel sequencing; 454; Pyrosequencing; amplicon sequencing; enrichment; DNA barcodes; Genetics; Genetik;

    Sammanfattning : Advances in sequencing technologies constantly improves the throughput andaccuracy of sequencing instruments. Together with this development comes newdemands and opportunities to fully take advantage of the massive amounts of dataproduced within a sequence run. LÄS MER

  7. 15. Consumption patterns and excretion in aquatic food websenrichment

    Författare :Anders Persson; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; trophic interactions; translocation; biomanipulation; enrichment; phosphorus; model; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : This thesis links biogeochemical cycling to classical ecology. Predictions derived from food chain theory, based on Lotka-Volterra type of interactions, were tested in aquatic environments with the main hypothesis that consumers affect lower levels of organization by both predation and excretion of limiting nutrients.
