  1. 1. Buffer optimisation for an improved cell separation using Acoustophoresis with Polystyrene particles, Jurkat, MCF-7 and DU-145 cell lines

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Lovisa Silversand; [2023]
    Keywords : Technology and Engineering;

    Abstract : Akustophores är rörelse av partiklar/celler under inverkan av ljud. Partikel- och cell separation är en applikation som kan utföras av akustophores. Detta är en viktig teknik eftersom den kan avslöja viktig information om sjukdomar och celler och därigenom förbättra valet av behandling inom sjukvården. READ MORE

  3. 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

  4. 3. Improving cell secretome analysis and bacteria evolution by means of acoustophoresis

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Moritz Leuthner; [2020]
    Keywords : acoustophoresis; acoustofluidic; lab-on-a-chip; acoustic streaming; acoustic radiation force; particle trapping; particle washing; bulk acoustic waves; BAW; media exchange; cell manipulation;

    Abstract : In both, cell secretome analysis and bacteria evolution, controlled handling of particles with a few to sub-micrometers in size and media exchange are inevitable in order to investigate body fluid’s proteins or change the surrounding culture conditions for pivoted evolution. Typically, nanofiltration and ultra-centrifugation are employed which can lead to cell damage, need large sample volumes and have a high sample loss. READ MORE

  5. 4. Enrichment of microparticles in droplets using acoustophoresis

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Klara Björnander Rahimi; [2018]
    Keywords : droplet microfluidics; acoustophoresis;

    Abstract : Acoustophoresis is a label free method where the acoustic radiation force is used to manipulate microparticles inside microfluidic channels. The magnitude of the force is dependent of several parameters, which include the density, speed of sound and size of the microparticles, as well as the amplitude of the pressure waves. READ MORE

  6. 5. 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
