    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

  3. 7. Boundary integral methods for fast and accurate simulation of droplets in two-dimensional Stokes flow

    Författare :Sara Pålsson; Anna-Karin Tornberg; Shravan Veerapaneni; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : Accurate simulation of viscous fluid flows with deforming droplets creates a number of challenges. This thesis identifies these principal challenges and develops a numerical methodology to overcome them. Two-dimensional viscosity-dominated fluid flows are exclusively considered in this work.

  4. 8. Fast and accurate integral equation methods with applications in microfluidics

    Författare :Ludvig af Klinteberg; Anna-Karin Tornberg; Mary-Catherine Kropinski; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This thesis is concerned with computational methods for fluid flows on the microscale, also known as microfluidics. This is motivated by current research in biological physics and miniaturization technology, where there is a need to understand complex flows involving microscale structures. Numerical simulations are an important tool for doing this. LÄS MER

  5. 9. Acoustic manipulation for cell and spheroid cellomics

    Författare :Karl Olofsson; Martin Viklund; Maria Tenje; KTH; []
    Nyckelord :Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Ultrasonic standing wave (USW) particle manipulation has during the last two decades matured into a valuable tool to combine with microfluidics. Acoustophoresis, migration through sound, is the result of the acoustic radiation force acting on particles suspended in an acoustic field.

  7. 10. MEMS Interfaces for Bioanalysis Systems

    Författare :Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

    Sammanfattning : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. LÄS MER
