   Sammanfattning : X-ray imaging is a group of techniques using electromagnetic radiation of high energy. The ability to quickly visualize internal structures in thick opaque objects has made it an indispensable tool in research, medicine, and industry. LÄS MER

4. 18. Synthesis, Surface Modification, and Characterization of Metal Oxide Nanoparticles : Nanoprobes for Signal Enhancement in Biomedical Imaging

   Författare :Linnéa Selegård; Kajsa Uvdal; Pentti Tengvall; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : In this thesis we investigate crystalline metal oxide nanoparticles of our own design to obtain nanoprobes for signal enhancement and bioimaging purposes. We report fabrication, surface modification and characterization of nanoparticles based on zinc (Zn), and rare earths (i.e. gadolinium (Gd) and europium (Eu)) singly and in combination. LÄS MER

5. 19. Preclinical X-Ray Fluorescence Imaging with Multifunctional Nanoparticles

   Författare :Giovanni Marco Saladino; Hans Hertz; Muhammet Toprak; Stefan Andersson-Engels; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

   Sammanfattning : X-ray fluorescence imaging (XFI) is an emerging technique for preclinical studies, characterized by high resolution, specificity, and sensitivity. It relies on nanoparticles (NPs) as contrast agents, which must be constituted of specific elements that match the X-ray source energy for detection. LÄS MER

7. 20. High resolution laboratory x-ray tomography for biomedical research : From design to application

   Författare :Till Dreier; Lund Medicinsk strålningsfysik; []
