    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  4. 8. Deacetylated Hyaluronan : Exploration of deacetylation techniques for hyaluronan (oligo and polysaccharides)

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Sima Mardini; Hanna Björk; Marcus Möller; Carl Lagergren; Oscar Samuelsson; [2023]
    Nyckelord :hyaluronic acid; deacetylated hyaluronan; N-deacetylation; re-acetylation; hydrogels;

    Sammanfattning : Hyaluronic acid is an organic polysaccharide with a wide range of uses in medical and cosmetic industries due to its physiological properties. Crosslinked hyaluronic acid is a commonly used filler agent because of its water retention capabilities. N-deacetylation can be performed to enable new derivatives of hyaluronic acid. LÄS MER
