    Författare :Janosch D. Hauser; Niclas Roxhed; Göran Stemme; Charles Mace; KTH; []

    Sammanfattning : Sample preparation is an integral part of bio-medical analysis routines, as it makes specimens of interest compatible with downstream instrumentation. Correct and proper sample preparation is of critical importance for reliable analysis results. LÄS MER

  4. 4. Capillary driven devices for patient-centric diagnostics

    Författare :Gabriel Lenk; Niclas Roxhed; Göran Stemme; Jens Ducrée; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Flexible and Stretchable Biointerfacing for Healthcare Diagnostics
