    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fe3O4; mSiO2; core-shell; MRI; multifunctional; PNIPAAm; LCST; gold; nanorod; nitric acid; AR; MDDC; biocompatibility; immunomodulation; Materials chemistry; Materialkemi;

    Sammanfattning : In recent years, nanostructured materials incorporated with inorganic particles and polymers have attracted attention for simultaneous multifunctional biomedical applications. This thesis summarized three works, which are preparation of mesoporous silica coated superparamagnetic iron oxide (Fe3O4@mSiO2) nanoparticles (NPs) as magnetic resonance imaging T2 contrast agents, polymer grafted Fe3O4@mSiO2 NPs response to temperature change, synthesis and biocompatibility evaluation of high aspect ratio (AR) gold nanorods.

  3. 2. Macromolecular Engineering by Surface-Initiated ATRP: : New Nanomaterials for Bioapplications

    Författare :Lingdong Jiang; Tillämpad biokemi; []
    Nyckelord :Nanohybrid; Polymer brush; ATRP; Bioseparation; Bioconjugate;

    Sammanfattning : The objective of this thesis is to investigate the synthesis of well-defined polymer nanohybrid materials bearing desirable functionality via surface-initiated atom transfer radical polymerization (SI-ATRP) for potential bioapplications.SI-ATRP is an excellent controlled radical polymerization (CRP) method for the synthesis of polymer nanohybrid by growing polymer brushes (chains) from an interface, which allows precise control over polymer composition, topology, and functionality.
