    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. Capillary driven devices for patient-centric diagnostics

    Författare :Gabriel Lenk; Niclas Roxhed; Göran Stemme; Jens Ducrée; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capillary driven; Microfluidic; Dissolvable valves; PVA; Volume metering; Dried Blood Spots; DBS; Dried Plasma Spots; DPS; Medicinsk teknologi; Medical Technology;

    Sammanfattning : Lateral flow assays is an example of a successful microfluidic platform relying on passive fluid transport, making them suitable for patient-centric and point-of-care applications. Flow control and valving in capillary driven devices typically rely on design-imprinted functions and operations which can be a limiting factor. LÄS MER
