  1. 1. Evaluation of electrospun lignin/polyvinyl alcohol/cellulose nanofiber mats

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lisa Johansson Carne; [2021]
    Nyckelord :Electrospinning; lignin; polyvinyl alcohol; cellulose nanofiber; wound dressing;

    Sammanfattning : Polymeric electrospun nanofiber mats have recently emerged as a promising alternative to conventional wound dressings for non-healing wounds. Its large surface area, porosity and scalability are only a few of the promising characteristics of electrospun nanofibers. LÄS MER

  3. 2. Cellulose nanocrystals functionalized cellulose acetate electrospun membranes for adsorption and separation of nanosized particles

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :José Ignacio Del Río De Vicente; [2021]
    Nyckelord :Electrospinning; Cellulose Nanocrystals; Filtration; Adsorption; Cellulose Acetate Fibers;

    Sammanfattning : Filtration and separation technologies remain as one of the biggest challenges humanity currently faces. The separation of different elements such as bacteria, viruses, heavy metals, particles, and chemical agents require the development of multifunctional membranes. LÄS MER

  5. 4. 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.

  7. 5. Effects of Different Laminins on Human Neural Progenitor Cells Cultured in 3D Electrospun Fibers

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

    Författare :Karl Vesterlund; [2019]
    Nyckelord :two-dimensional; three-dimensional; Alamar Blue; cell culture; drug development; extra-cellular matrix; electrospinning; immunocytochemistry; laminin; polycaprolactone; polymerase chain reaction; western blot; applied biochemistry; tillämpad biokemi; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : A low success rate of drug candidates in clinical trials, and especially in brain research, motivates development of better screening models. Hence, in neuroscience and many other fields of Life Science, development of more physiological relevant experimental cell-based models is motivated. LÄS MER
