    Författare :Carmen Mihaela Vogt; Mamoun Muhammed; Alfonso Garcia-Bennett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Functional materials; Funktionella material;

    Sammanfattning : The necessity for synthesis of nanoparticles with well controlled size and morphology emerged with the development in recent years of novel advanced applications especially in biomedical related fields. These applications require nanoparticles with more complex architecture such as multifunctional nanoparticles (i.e. LÄS MER

  4. 13. Multifunctional nanomaterials for diagnostic and therapeutic applications

    Författare :Andrea Fornara; Mamoun Muhammed; Patrick Saulnier; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Sammanfattning : In the past few years, the use of nanostructured materials in medical applications hasdramatically increased, both in the research phase and for clinical purposes, due to thepeculiar properties and the ability of such materials to interact at a similar scale withbiological entities. In this thesis, we developed tailored magnetic multifunctionalnanoparticles for diagnostic and therapeutic applications, such as detection ofbiomolecules, simultaneous enhanced magnetic resonance imaging (MRI), fluorescentvisualization and controlled drug release.

  5. 14. Photoemission and Characterization of Neutrophils and Nanoparticles : Energy Mapping and Elemental Composition with sub-µm Resolution

    Författare :Andreas Skallberg; Kajsa Uvdal; Christelle Prinz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Imaging and visualization of cells and tissues are important when studying various biological phenomena. The ability to provide spatial information with molecular and chemical specificity may increase our insight and understanding of biological problems within life sciences. LÄS MER

  7. 15. Engineered core : shell nanoparticles: synthesis, characterisation, and biocompatibility studies

    Författare :Carmen Mihaela Vogt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Superparamagnetic iron oxide nanoparticles (SPIONs) have emerged as promising contrast agents for Magnetic Resonance Imaging (MRI). Some SPIONs are already approved for clinical use. Coating of these nanoparticles with an additional biocompatible layer serves to improve the colloidal stability and biocompatibility. LÄS MER
