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
3. Effects of Spin-Orbit Interactions in Ferromagnetic Metal Nanoparticles
Sammanfattning : This thesis is a theoretical investigation of the effects of spin-orbit (SO) interactions in ferromagnetic metal nano-particles. Part I of the thesis is devoted to an elementary introduction of the research field, including recent experimental advances which partly motivated the work presented here. LÄS MER
4. Investigation of nanoparticle-cell interactions for development of next generation of biocompatible MRI contrast agents
Sammanfattning : Progress in synthesis technologies and advances in fundamental understanding of materials with low dimensionality has led to the birth of a new scientific field, nanoscience, and to strong expectations of multiple applications of nanomaterials. The physical properties of small particles are unique, bridging the gap between atoms and molecules, on one side, and bulk materials on the other side. LÄS MER
5. Multimodal sentinel lymph node imaging using nanoscale-tailored particles; The importance of particle size
Sammanfattning : As a cancer grows it will, at a certain stage of disease progression, start spreading in the body. For several types of cancer this spreading will first occur through the lymphatic system and the first place where metastatic cell will be encountered is the first lymph node that drains the area where the tumor is located.
