  1. 1. General Defocus Particle Tracking

    University essay from KTH/Tillämpad fysik

    Author : Joakim Anderberg; [2023]
    Keywords : General Defocus Particle Tracking; ultrasonic standing waves; microscopy; microchip; single plane particle tracking; levitation; Generel ur-fokus partikel spårning; stående ultraljudsvågor; mikroskopi; mikorchip; enkelplans partikel spårning; levitation;

    Abstract : Three-dimensional particle tracking is a valuable tool in microfluidics for obtaining information about a system. General Defocus Particle Tracking (GDPT) is a straightforward method of 3D particle tracking that only requires a single-camera plane, making it applicable to existing equipment in a laboratory.

  2. 2. Improving bright-field images for tracking particles with Defocustracker

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Carl Lundin; [2022]
    Keywords : Defocustracker; GDPT; particle tracking; bright-field; acoustophoresis; Laplacian of Gaussian; Technology and Engineering;

    Abstract : Acoustophoresis is a cell separation technology where particles or cells are suspended in a fluid container and subject to acoustic standing waves. The standing waves exerts an acoustic radiation force on the particles, pushing them towards the nodal plane. READ MORE

  3. 3. 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.

  4. 4. Suppression of acoustic streaming in liquids of inhomogeneous density and compressibility

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Dzenan Hajdarovic; [2016]
    Keywords : inhomogeneous medium; density gradients; acoustic streaming; iso-acoustic focusing; acoustophoresis; microchannel; microfluidics; general defocusing particle tracking; astigmatic particle tracking; Technology and Engineering;

    Abstract : This thesis provides strong evidence that acoustic streaming is suppressed when using liquids of inhomogeneous density and compressibility in acoustophoresis. Manipulation of extremely small particles in acoustophoresis is something that usually is impaired by acoustic streaming. The project was divided into three aims. READ MORE
