Archaeal tetraether lipid coatings - A strategy for the development of membrane analog spacer systems for the site-specific functionalization of medical surfaces
Liefeith, Klaus; Frant, Marion; Muller, Ute; Stenstad, Per Martin; Johnsen, Heidi; Schmid, Ruth (Peer reviewed; Journal article, 2018)The primary goal of our investigation was the development of a versatile immobilization matrix based on archaeal tetraether lipids that meets the most important prerequisites to render an implant surface bioactive by binding ... -
Encapsulation of salmon oil using complex coacervation: Probing the effect of gum acacia on interfacial tension, coacervation and oxidative stability
Glomm, Wilhelm; Molesworth, Peter Patrick; Yesiltas, Betül; Jacobsen, Charlotte; Johnsen, Heidi (Peer reviewed; Journal article, 2023)The molecular characteristics of the food-grade polysaccharide gum acacia may vary depending on source, which could in turn significantly affect its behaviour as thickener, emulsifier and as a wall material in microencapsulation. ... -
High-throughput assay for effect screening of amphotericin B and bioactive components on filamentous Candida albicans
Haslene-Hox, Hanne; Nærdal, Guro Kruge; Mørch, Ýrr Asbjørg; Hageskal, Gunhild; Tøndervik, Anne; Vikenes, Anette; Johnsen, Heidi; Klinkenberg, Geir; Sletta, Håvard (Peer reviewed; Journal article, 2022) -
Immobilized protease on magnetic particles for enzymatic protein hydrolysis of poultry by-products
Glomm, Wilhelm; Wubshet, Sileshi Gizachew; Lindberg, Diana; Dankel, Katinka R.; Afseth, Nils Kristian; Stenstad, Per Martin; Johnsen, Heidi (Peer reviewed; Journal article, 2021)Immobilization of enzymes onto magnetic particles can potentially allow for enzyme reuse, which can significantly reduce the cost associated with e.g. enzymatic protein hydrolysis (EPH) of fish and meat by-products. Here, ... -
Microencapsulation of Peppermint Oil by Complex Coacervation and Subsequent Spray Drying Using Bovine Serum Albumin/Gum Acacia and an Oxidized Starch Crosslinker
Glomm, Wilhelm Robert; Molesworth, Peter Patrick; Sandru, Eugenia-Mariana; Truong, Thuy le; Brunsvik, Anders; Johnsen, Heidi (Peer reviewed; Journal article, 2021)Most liquid food flavours such as essential oils are volatile and prone to degradation in the presence of oxygen, light, moisture and high temperatures. Microencapsulation of volatile ingredients prior to use in food or ... -
Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery
Mørch, Ýrr Asbjørg; Hansen, Rune; Berg, Sigrid; Åslund, Andreas; Glomm, Wilhelm; Eggen, Siv; Schmid, Ruth; Johnsen, Heidi; Kubowicz, Stephan; Snipstad, Sofie; Sulheim, Einar; Hak, Sjoerd; Singh, Gurvinder; McDonagh, Birgitte Hjelmeland; Blom, Hans; Davies, Ruth Catharina de Lange; Stenstad, Per Martin (Journal article; Peer reviewed, 2015)Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology ... -
Uptake and toxicity of methylmethacrylate-based nanoplastic particles in aquatic organisms
Booth, Andy; Hansen, Bjørn Henrik; Frenzel, Max; Johnsen, Heidi; Altin, Dag (Journal article; Peer reviewed, 2015)The uptake and toxicity of 2 poly(methylmethacrylate)-based plastic nanoparticles (PNPs) with different surface chemistries (medium and hydrophobic) was assessed using aquatic organisms selected for their relevance based ...
