There is an increasing interest in the modification of alginates ... -
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 ... -
Microbial Therapeutics and Oral Delivery Systems – An Evaluation of Microencapsulation of Microbiota
Midtvedt, Simon Lunde (Master thesis, 2020)The understanding of the role of microorganisms in human health and disease has rapidly expanded in recent years. The emerging field of microbial therapeutics refers to the notion of introducing exogenous microbes to the ... -
Migration of T-cells in a multi-compartment hydrogel model of inflammation
Damigos, Spyridon (Master thesis, 2020)In the present work multi-compartmental hydrogels were established in order to study T-cell migration in 3D. The main approach that was developed for the fabrication of the hydrogel systems, was based on the incorporation ... -
