  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. 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.

  5. 4. Microfluidic Chip development for acoustophoresis assisted selective cell sorting

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

    Author : mohd adnan faqui shahzad; [2017]
    Keywords : ;

    Abstract : Analysis of blood samples is one of the major steps in diagnosing pathological conditions like cancer. The upstream sample preparation for the pathological cell analysis from complex biological fluid like blood, involves selective cell sorting. It can be achieved using fluorescently activated or magnetically activated cell sorters. READ MORE

  6. 5. Statistical Signal Processing of Ultrasonic Signals in Norway Spruce Infected by Root and Butt Rot

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Annika Tonteri; Aferdita Aliu; [2011]
    Keywords : Technology and Engineering;

    Abstract : Root and butt rot in Norway spruce is costly for the forest industry and finding alternative noninvasive, efficient and cheap methods is thus of great interest. Detection of root and butt rot in Norway Spruce by analysis of an ultrasonic signal sent through standing trees could be a good alternative method. READ MORE
