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. Improving image quality of a streak camera using periodic shadowing

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Författare :David-Gabriel Lange; [2021]
   Nyckelord :combustion physics; laser; lock-in amplification; laser induced fluorescence; periodic shadowing; Rhodamine B; streak camera; Mode-locking; microfluidics; fluorescence lifetime imaging; Physics and Astronomy;

   Sammanfattning : Stray light suppression using a method inspired by lock-in amplification, called periodic shadowing, is examined and demonstrated for a measurement involving a streak camera. The experiment consists of resolving the fluorescent decay of the dye Rhodamine B (RhB) and examining both the rise and the decay of the fluorescence. LÄS MER
