  1. 1. Sustained and triggered release by microencapsulation

    Författare :Viktor Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cellulose; controlled release; microencapsulation; solution blown;

    Sammanfattning : Uncontrolled growth of microorganisms is problematic in areas ranging from wound care to aquaculture and ship hulls. In chronic and hard-to-heal wounds, a bacterial biofilm can impair wound healing. LÄS MER

  3. 2. Physico-Chemical Investigations of Bilayer Discs and Related Lipid Structures Formed in Liposomal Systems Intended for Triggered Release

    Författare :Maria Sandström; Katarina Edwards; Mats Almgren; Tommy Nylander; Uppsala universitet; []
    Nyckelord :Physical chemistry; liposome; triggered release; pH-sensitive liposomes; temperature-sensitive liposomes; drug partitioning; cryo-TEM; discs; Fysikalisk kemi;

    Sammanfattning : This thesis describes results from fundamental studies of liposomes intended for drug delivery and pH or temperature triggered release. In addition, the effect of lipid composition on bilayer disc formation and a potential application of the bilayer discs were investigated. LÄS MER

  4. 3. From Macromolecular Design to Supramolecular Self-assembly

    Sammanfattning : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

  5. 4. Bacteria-responsive materials for drug delivery

    Författare :Marina Craig; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; triggered release; multilayer; controlled release; Layer-by-layer; nanofilm; infection; enzymatic degradation;

    Sammanfattning : The number of diabetics, obese individuals and other patients carrying other lifestyle diseasesis increasing worldwide. At the same time the population is ageing. These patients all sufferfrom poor blood circulation, which often gives rise to non-healing, or chronic, wounds. Thus,the number of chronic wounds is also increasing at a fast pace. LÄS MER

  7. 5. Peptide-Liposome Model Systems for Triggered Release

    Författare :Camilla Skyttner; Daniel Aili; Karin Enander; Fredrik Höök; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Liposomes are widely used in drug delivery to improve drug efficacy and to reduce side effects. For liposome-encapsulated drugs to become bioavailable and provide a therapeutic effect they must be released, which typically is a slow process that primarily relies on passive diffusion, liposome rupture or endocytotic uptake.
