  4. 2. Functional and Renewable Galactoglucomannan-based Hydrogels

    Author : Jens Voepel; Ann-Christine Albertsson; Ulrica Edlund; Gunnar Henriksson; Margaretha Söderqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polysaccharides; hydrogels; swelling; crosslinking; hemicellulose; release; polysackarider; hemicellulosa; hydrogel; läkemedelsfrisättning; förnyelsebar; tvärbindning.; Functional materials; Funktionella material;

    Abstract : Polysaccharides represent an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Here they are, due to their natural diversity found in many special applications, e.g. in the biomedical sector. READ MORE

  5. 3. On the phase behaviour of hydrogels : A theory of macroion-induced core/shell equilibrium

    Author : Jonas Gernandt; Per Hansson; Göran Frenning; Renko de Vries; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polymer; polyelectrolyte; surfactant; thermodynamics; elasticity; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Colloidal macroions are known to interact very strongly with oppositely charged polyionic hydrogels. Sometimes this results in a non-uniform distribution of the macroions within the gel, a phenomenon that is not fully understood. READ MORE

  6. 4. Amphiphilic hydrogels functionalized with antimicrobial peptides for wound care

    Author : Edvin Blomstrand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infections; Antimicrobial peptides; hydrogels; wound care; lyotropic liquid crystals; antibacterial surfaces; amphiphilic polymers; surface functionalization;

    Abstract : Bacteria have the potential to cause significant harm to us when found in places where we do not want them, such as in wounds. Through the last century, the gold standard of eradicating bacteria in these cases has been with antibiotics. READ MORE

  7. 5. Chemical micropatterning of hyaluronic acid hydrogels for brain endothelial in vitro cell studies

    Author : Ana Maria Porras Hernández; Maria Tenje; Martin Dufva; Uppsala universitet; []
    Keywords : Micropatterning; hydrogels; hyaluronic acid; brain endothelial cells; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : The building blocks of human tissues are cells. The cells interact and respond to the characteristics of their local microenvironment. The cellular microenvironment is formed by three main components, the extracellular matrix, neighbouring cells and signalling molecules. READ MORE
