    Sammanfattning : The application of nanoparticles (NPs) in different technologies has led to tremendous advancement in those fields.  Moreover, there is growing interest in application of ultra-small NPs (USNPs) at 1-3 nm due to their distinct molecule like features. Parallel to these promises, there is a growing concern regarding their safety. LÄS MER

  4. 3. Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation

    Detta är en avhandling från Lund University, Faculty of Science, Department of Medical Radiation Physics

    Författare :Renata Madru; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018-04]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron oxide; nanoparticles; SPIONs; PET-MRI; SPECT-MRI; SPECT-MRI- optical imaging; sentinel lymph node; SNL;

    Sammanfattning : Bröst- och hudcancerceller sprider sig via lymfatiska systemet och fastnar i en eller två regionala sentinel lymfnoder (SLN) där de med stor sannolikhet växer till metastaser. Därför är SLN-biopsier och relaterade histopatologiska undersökningar viktiga vid cancerdiagnostiken för att bestämma sjukdomsstatus och att från denna kunna bestämma rätt behandling. LÄS MER
