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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Prasanna Surana; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Polymerkemi

    Author : Björn Stenestam; [2021]
    Keywords : ;

    Abstract : 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. Design, evaluation and use of a microfluidic device for automated production of mucin microparticles for cell encapsulation for diabetes therapy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Bharathesh Badadamath; [2019]
    Keywords : ;

    Abstract : Droplet microfluidics has prevalent growth in a wide range of applications in the life science field. This project is one such example where we used a droplet microfluidics tool for treating diabetes mellitus type 1. Mucin hydrogels (Muc-gels) modulate the immune response driving biomaterialinduced fibrosis.[1]. 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. Synthesis and characterization of amine-functionalized microgel particles and their subsequent assembly into colloidal molecule-like clusters by droplet-based microfluidics

    University essay from Lunds universitet/Kemiska institutionen

    Author : Emil Gustafsson; [2015]
    Keywords : Physical chemistry; fysikalisk kemi; Chemistry;

    Abstract : The ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subsequent assembly into clusters using droplet-based microfluidics, with the goal of forming responsive colloidal molecules with well-defined valency.
