• Characterization and Properties of Hydrogels Made from Neutral Soluble Chitosans 

      Franzen, Henry M; Draget, Kurt Ingar; Langebäck, Joakim; Nilsen-Nygaard, Julie (Journal article; Peer reviewed, 2015)
      The current paper focuses on the preparation and some characteristics of viscoelastic hydrogels, ViscoGels™, made from chitosans having a random acylation pattern. Three different chitosan batches with a high fraction of ...
    • Chitosan: Gels and interfacial properties 

      Nilsen-Nygaard, Julie; Strand, Sabina P.; Vårum, Kjell Morten; Draget, Kurt Ingar; Nordgård, Catherine Taylor (Journal article; Peer reviewed, 2015)
      Chitosan is a unique biopolymer in the respect that it is abundant, cationic, low-toxic, non-immunogenic and biodegradable. The relative occurrence of the two monomeric building units (N-acetyl-glucosamine and d-glucosamine) ...
    • Direct Determination of Chitosan–Mucin Interactions Using a Single-Molecule Strategy: Comparison to Alginate–Mucin Interactions 

      Haugstad, Kristin Elisabeth; Håti, Armend Gazmeno; Nordgård, Catherine Taylor; Adl, Patricia S.; Maurstad, Gjertrud; Sletmoen, Marit; Draget, Kurt Ingar; Dias, Rita de Sousa; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2015)
      Aqueous chitosan possesses attractive interaction capacities with various molecular groups that can be involved in hydrogen bonds and electrostatic and hydrophobic interactions. In the present paper, we report on the direct ...
    • Mechanical properties of composite hydrogels of alginate and cellulose nanofibrils 

      Aarstad, Olav Andreas; Heggset, Ellinor Bævre; Pedersen, Ina S.; Bjørnøy, Sindre Hove; Syverud, Kristin; Strand, Berit Løkensgard (Journal article; Peer reviewed, 2017)
      Alginate and cellulose nanofibrils (CNF) are attractive materials for tissue engineering and regenerative medicine. CNF gels are generally weaker and more brittle than alginate gels, while alginate gels are elastic and ...
