  1. 1. Buffer modification: A case study with polystyrene beads, DU145-, and MCF7 cell lines

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Olivia Hansson Rengbrandt; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Separation of cancer cells gives advantages in understanding the disease, guiding treatment decisions, and facilitating drug development. Overall, separation plays an important role in biological research. Acoustophoresis is a technique that utilizes acoustic waves to separate particles and cells suspended in a buffer medium. LÄS MER

    Sammanfattning : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. LÄS MER

  7. 5. Nd-doped Upconverting Nanoparticles for Deep Tissue Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Hugo Söderlund; [2014]
    Nyckelord :fluorescence imaging; Upconverting nanoparticles; biophotonics; Nd-doped comparison; Physics and Astronomy;

    Sammanfattning : During the last decade, upconverting nanoparticles (UCNPs) doped with rare-earth (RE) ions have been extensively studied in the field of biophotonics. Due to their unique properties of anti- Stokes shifted luminescence and with excitation and emission wavelengths optimal for biomedical imaging, they have become an interesting class of fluorescent contrast agents.
