Hybrid nanomaterials possessing dual magnetic/optical properties are of considerable interest to many areas, ranging from material science to medicine and biology. They are promising for a broad range of applications including catalysis, energy conversion, biological separation, medical diagnosis and treatment. Anisotropic magnetic-optical nanoparticles give better or new properties compared to spherical ones due to their high curvature and polarization-sensitive geometry. However, the engineering of compact and uniform anisotropic magnetic-optical core-shell nanoparticles remains a major challenge. The work in this thesis is aimed at the preparation and characterization of magnetic-optical core-shell hybrid NPs in different shapes and sizes. Iron oxide-gold core-shell nanoparticles in spherical, oval and pin shapes were prepared. Our studies have shown that iron oxide-gold core-shell nanoparticles, despite the shapes, exhibit 10 times better absorption properties compared to solid gold nanoparticles. The availability of these nanoparticles would make an important impact in biomedicine, material science and other fields.
