  1. 1. How Topography Influences the Fate of Human Neural Progenitor Cells

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Författare :Jacob Karlström; [2020]
    Nyckelord :biomaterials; cell culture; electrospinning; nanofibers; 3d; neural progenitor cells; in vitro models; nanotopography; blebbistatin; mechanotransduction; nucleus analysis; immunocytochemistry; differentiation; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering;

    Sammanfattning : Novel biomimetic three-dimensional scaffolds have emerged over the last decades, and are promising for applications in regenerative therapies, as well as in in vitro disease modelling and drug testing. Thanks to their added dimension, these scaffolds are able to more accurately mimic the topography of native cellular microenvironments compared to traditionally used two-dimensional culture substrates.

  3. 2. Acoustic Characterization of the Cellulose-coated Perfluorocarbon Droplets based on Phase Velocity Measurements

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

    Författare :Emma Lindroth; [2020]
    Nyckelord :Ultrasound; Droplets; Contrast agent; Cellulose; Perfluorocarbon; Acoustic characterization; Non-destructive evaluation; Phase velocity; Bulk modulus; Compressibility;

    Sammanfattning : Today, microbubbles are one of the most commonly used ultrasound contrast agents, since their high compressibility results in a strongly scattered signal. Despite this advantage, microbubbles experience limitations by the decreased stability and large diameter. LÄS MER

  4. 3. Controlled deposition and alignment of electrospun PMMA-g-PDMS nanofibers by novel electrospinning setups

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Bashar Haseeb; [2011]
    Nyckelord :Electrospinning; nanofibers; nanofiber alignment; PMMA-g-PDMS; controlled deposition; triple electrode.;

    Sammanfattning : Electrospinning is a useful technique that can generate micro- and nano-meter sized fibers from polymer materials. Modification of the electrospinning parameters and apparatus can generate nanofibers for use in diverse applications ranging from tissue engineering to nanocomposite fabrication; however, electrospun fibers are typically collected in a random orientation and over large areas limiting their applications.
