  1. 1. Characterization of Agarose Microdroplet Properties for Acoustic Trapping of Encapsulated Bacteria and On-chip DNA Extraction

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Tinde Höjer; [2021]
    Nyckelord :;

    Sammanfattning : The aim of this project was to investigate if the translation of a DNA extraction protocol to on-chip, for the purpose of reducing the total assay time, would be possible. This was to be enabled by encapsulating bacteria in hydrogel microdroplets that would then be acoustically trapped in a microfluidic system. LÄS MER

  3. 2. Acoustic trapping of sub-micrometreparticles within microfluidics particles within microfluidics

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Polymerkemi

    Författare :Björn Stenestam; [2021]
    Nyckelord :;

    Sammanfattning : The aim of this project was to prove that a pre-existing standardmethod for bacterial-DNA extraction can be reduced down to the microscale and in doing so be used in an on-chip setting.The first phase in this project was to identify an appropriate methodand material for droplet generation.

  4. 3. 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

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

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Sammanfattning : 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. LÄS MER

  7. 5. Improvements in reproducibility, throughput and capacity of microfluidic acoustic trapping systems

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Daniel Glifberg; [2016]
    Nyckelord :acoustic trapping; microfluidics; acoustofluidics; Technology and Engineering;

    Sammanfattning : Acoustic trapping is a novel technology that allows for microfluidic sample preparation and pretreatment. The aim of this text is to give the reader a general insight in microfluidics with a focus on acoustic trapping. LÄS MER
