  1. 1. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Jonathan Karlsson; [2023]
    Nyckelord :Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

    Sammanfattning : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

  3. 2. Measuring Acoustic Mobility of Particles by Particle Tracking Velocimetry

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Alexander Edthofer; [2022]
    Nyckelord :acoustophoresis; microfluidics; polystyrene; cells; particle tracking velocimetry; Technology and Engineering;

    Sammanfattning : Acoustophoresis is a method to manipulate and move cells or particles suspended in a medium using acoustic waves. The speed of the acoustophoretic motion depends on the cells' acoustic mobility, i.e. their size, density and compressibility relative to the medium. LÄS MER

  4. 3. Determining the Acoustic Mobility of Breast Cancer Cells

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Simon Olsson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Breast cancer is one of the most common forms of cancer detected in women. Its heterogeneity and large mutational landscape requires treatment strategies which varies between patients. Triple negative breast cancer (TNBC) is a particularly aggressive subtype which 12-17 \% of breast cancer patient develop. LÄS MER

  5. 4. Investigation of acoustic whole blood plasmapheresis for minimization of endogenous blood loss in neonatal care

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Tobias Lindgren; [2021]
    Nyckelord :Acoustophoresis; peristaltic pump; flow cytometry; plasmapheresis; whole blood; extremely premature infants; Microfluidics; Technology and Engineering;

    Sammanfattning : Early erythrocyte transfusion is common in infants born extremely premature. Research has shown that these children are at greater risk of morbidity later in life, and that iatrogenic blood loss from blood sample analysis is one of the contributing factors to the need for transfusions.

  7. 5. Evaluation of OSTE-hybrid materials for acoustophoresis applications

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Elin Forss; [2020]
    Nyckelord :Acoustophoresis; off-stoichiometry-thiol-enes; OSTE; microfluidics;

    Sammanfattning : This project aimed at exploring new hybrid materials to be used for acoustophoresis applications. Acoustophoresis can be used to manipulate particles inside a microfluidic channel by creating ultrasound standing waves within the channel [1]. This can be used for cell separation [2] or trapping of particles [3]. LÄS MER
