  2. 6. 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

  4. 7. Nanocellulose Oxidation - Fundamentals and Application in Hydrogels

    Author : Saül Llacer Navarro; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sulfate half-ester group; cellulose oxidation; polysaccharide hydrogels; Nanocellulose;

    Abstract : The adaptable surface chemistry of cellulose nanocrystals (CNCs) makes them outstanding; it provides colloidal stability, which is essential for engineering use, to commercially-available CNCs. Colloidal stability is achieved by the bulky negatively-charged sulfate half-ester groups on the surface that it manufactures itself via the use of sulfuric acid. READ MORE

  5. 8. Structural Studies of Hyaluronan Hydrogels

    Author : Frida Wende; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Hydrogels consist of cross-linked polymer networks with the ability to absorb large amounts of water. In this thesis, the structures of hydrogels consisting of hyaluronic acid (HA) cross-linked by 1,4-butanediol diglycidyl ether (BDDE) have been investigated. READ MORE

  6. 9. Synthesis of AcGGM Polysaccharide Hydrogels

    Author : Laleh Maleki; Ulrica Edlund; Anette Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hemicellulose; O-acetyl-galactoglucomannan; wood hydrolysate; hydrogel; radical polymerization; interpenetrating polymer network; click chemistry; thiol-ene; Michael addition; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Lignocellulosic biomass is believed to serve a prominent role in tomorrow’s sustainable energy and material development. Among the polysaccharide fractions of lignocellulosic biomass, the potential of hemicelluloses as a valuable material resource is increasingly recognized. READ MORE

  7. 10. Collagen Hydrogels for Regenerative Medicine

    Author : Justina Pupkaite; Peter Påhlsson; Erik Suuronen; May Griffith; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The need for regenerative therapies to repair damaged or deteriorated organs and tissues, such as heart, skin, and cornea, is rising due to donor shortage and aging of the world’s population. Many proposed regenerative therapeutic approaches include a combination of cells, bioactive compounds, and hydrogels. READ MORE
