    Sammanfattning : The thesis concerns polyelectrolyte gels in contact with oppositely charged proteins and surfactant micelles, and includes of four papers (I-IV). In paper I confocal Raman spectroscopy was introduced as a method to trace micelles and investigate the structure of gel-surfactant complexes, in phase separated gel spheres. LÄS MER

  2. 2. Experimental Design and Evaluation of Biocide Release from Microcapsules

    Sammanfattning : To protect a painted house façade from mold or algae, anti-growth agents are usually mixed in the paint. The protection of paint systems used in the past relied on heavy metals for protection and are banned today due to their negative impact on the environment. LÄS MER

  3. 3. Modification and Utilization of Wood Hydrolysates

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Marie Svensson; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; hemicellulose; microsphere; hydrogel;

    Sammanfattning : Polysaccharides have been used for many years in a variety of products such as food, fuel supply and industrial products. During recent years there has been an increasing interest in a group of polysaccharides, hemicelluloses, due to their highly availability, renewability and potentially low price. LÄS MER

  4. 4. Artificial receptors: New opportunities for the exploitation of molecularly imprinted polymers

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Lei Ye; Lunds universitet.; Lund University.; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioimmunoassay; Microsphere; Molecular imprinting; Drug determination; Cross-linking polymerisation; Combinatorial library; Chromatography; Chiral separation; Affinity adsorbent; Biosensor; Receptor; Biochemistry; Metabolism; Biokemi; metabolism; Biotechnology; Bioteknik;

    Sammanfattning : Molecular imprinting, method for creating artificial receptors that are mimics of biological antibodies and receptors, is based on the concept of creating substrate-specific recognition sites in polymeric matrices by means of template polymerisation. The polymeric receptors produced display favourable binding characteristics, such as high affinity and specificity towards the substrate molecules. LÄS MER

  5. 5. Small-Scale Absorbed Dose Modelling in Selective Internal Radiation Therapy Microsphere Distribution in Normal Liver Tissue

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Jonas Högberg; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clusters; dosimetry; heterogeneity; liver; microspheres; radioembolisation; simulations; SIRT; surgery; yttrium-90;

    Sammanfattning : Radioembolisation (RE), with yttrium-90 (90Y) labelled microspheres, is an increasingly common treatment method for unresectable liver tumours. The tolerable mean absorbed dose for normal liver (NL) tissue is higher in RE than in External Beam Radiation Therapy (EBRT); absorbed dose heterogeneity is thought to be one important reason, together with a low absorbed dose rate, but the knowledge of microsphere distributions is limited.
