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

    University essay from KTH/Tillämpad fysik

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

    Abstract : 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. Microfluidic flow splitter shape optimization for high throughput

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Christoffer Papamoustos Palmér; Joel Linder; [2023]
    Keywords : Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

    Abstract : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. READ MORE

  4. 3. Synthetic gel particle formation for acoustofluidic applications

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Thibaut Valery; [2022]
    Keywords : agarose gel particles; acoustofluidics; droplet generation; microfluidic chip; Technology and Engineering;

    Abstract : Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. READ MORE

  5. 4. Thermal Acoustic Flow inside an Ultrasound Resonator

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Enrico Corato; [2020]
    Keywords : Microfluidics; Ultrasound; Acoustofluidics; Thermal gradient; Thermoacoustic; Technology and Engineering;

    Abstract : This thesis aims at investigating the interaction between thermal gradients and acoustic fields in microfluidic devices. In the research branch of Acoustofluidics, which bridges together acoustics and fluid dynamics, inhomogeneity in the medium has gained great interest due to the novel physics behind and the potential in manipulating submicrometer particles.
