      Electrospinning is a process that has attracted significant interest in recent years. It provides the opportunity to produce nanofibers that mimic the extracellular matrix. As a result, it is possible to use the nonwovens ...
    • Injectable In Situ Crosslinking Hydrogel for Autologous Fat Grafting 

      Oskarsdotter, Kristin; Nordgård, Catherine Taylor; Apelgren, Peter; Säljö, Karin; Solbu, Anita Akbarzadeh; Eliasson, Edwin; Sämfors, Sanna; Sætrang, Henriette Elisabeth Myhr; Asdahl, Lise Cathrine; Thompson, Eric Malcolm; Troedsson, Christofer; Simonsson, Stina; Strand, Berit Løkensgard; Gatenholm, Paul; Kölby, Lars (Peer reviewed; Journal article, 2023)
      Autologous fat grafting is hampered by unpredictable outcomes due to high tissue resorption. Hydrogels based on enzymatically pretreated tunicate nanocellulose (ETC) and alginate (ALG) are biocompatible, safe, and present ...
    • Local structure of Ca2+ alginate hydrogels gelled via competitive ligand exchange and measured by small angle X-ray scattering 

      Yamamoto, K; Yuguchi, Yoshiaki; Stokke, Bjørn Torger; Sikorski, Pawel; Bassett, David (Journal article; Peer reviewed, 2019)
      Alginates, being linear anionic co-polymers of 1,4-linked residues β-d-ManA (M) and α-l-GulA (G), are widely applied as hydrogel biomaterials due to their favourable in vivo biocompatibility and convenient ionic crosslinking. ...
    • Mechanical Properties of Ca-Saturated Hydrogels with Functionalized Alginate 

      Dalheim, Marianne Øksnes; Omtvedt, Line Aanerud; Bjørge, Isabel M.; Akbarzadeh, Anita; Mano, Joao F.; Aachmann, Finn Lillelund; Strand, Berit Løkensgard (Journal article; Peer reviewed, 2019)
      In this work, the mechanical properties and stability of alginate hydrogels containing functionalized alginates (peptide and β-cyclodextrin) were studied. There is an increasing interest in the modification of alginates ...

      Einen, Caroline; Price, Sebastian Everard Nordby; Ulvik, Kim; Gjennestad, Magnus Aashammer; Hansen, Rune; Kjelstrup, Signe; Davies, Catharina de Lange (Peer reviewed; Journal article, 2023)
      Pulsed focused ultrasound (FUS) in combination with microbubbles has been shown to improve delivery and penetration of nanoparticles in tumors. To understand the mechanisms behind this treatment, it is important to evaluate ...
    • On the determination of mechanical properties of aqueous microgels-towards high-throughput characterization 

      Øvreeide, Ingrid Haga; Szydlak, Renata; Luty, Marcin; Ahmed, Husnain; Prot, Victorien Emile; Skallerud, Bjørn Helge; Zemła, Joanna; Lekka, Małgorzata; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2021)
      Aqueous microgels are distinct entities of soft matter with mechanical signatures that can be different from their macroscopic counterparts due to confinement effects in the preparation, inherently made to consist of more ...
