  1. 1. Active dielectrophoretic trapping for deterministic single-cell encapsulation in droplet microfluidics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Prasanna Surana; [2023]
    Nyckelord :negative dielectrophoresis; droplet microfluidics; low conductivity medium; cell viability; COMSOL electric field simulation; joule heating; Rhodamine B temperature measurement; microfluidic chip cleaning; negativ dielektrofores; droppmikrofluidik; medium med låg konduktivitet; cellviabilitet; COMSOL elektrisk fältsimulering; jouleuppvärmning; Rhodamine B temperaturmätning; mikrofluidisk chiprengöring;

    Sammanfattning : The research work focuses on optimizing various parameters for controlling cells using negative dielectrophoresis and entrapping them in droplet microfluidics. This is achieved by developing a conductivity medium, combining CytoRecovery, BSA, and EDTA, to maintain a steady count of single cells with good viability over an extended period. LÄS MER

  3. 2. Electrochemical strategies to retrieve lost capacity in Li-ion batteries by reversed Li-trapping

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi; Uppsala universitet/Strukturkemi

    Författare :Christopher Thulin; [2023]
    Nyckelord :Electrochemistry; lithium trapping; lithium-ion battery; diffusion;

    Sammanfattning : Since the transportation sector wants to move away from fossil fuels and become more dependen ton clean and green energy, the use of rechargeable batteries is a good solution. Lithium-based batteries work very well as rechargeable batteries in electric vehicles. LÄS MER

  4. 3. Development of Next-Generation Optical Tweezers : The New Swiss Army Knife of Biophysical and Biomechanical Research

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Daniel Nilsson; [2020]
    Nyckelord :optical tweezers; optical fiber tweezers; optical fiber; optical trapping; manipulation; optical force; cell trapping; biophysical; physicochemical; biomechanical; research; next-generation; raman spectroscopy; holographic optical tweezers;

    Sammanfattning : In a time when microorganisms are controlling the world, research in biology is more relevant than ever and this requires some powerful instruments. Optical tweezers use a focused laser beam to manipulate and probe objects on the nano- and microscale. LÄS MER

  5. 4. 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

  7. 5. 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
