Thanks to their remarkable properties, magnetic nanoparticles have secured a significant role in exploratory science, with their use now extending to numerous applications. This study focuses on the synthesis of biphasic magnetite–gold nanoparticles, aiming at their potential utilization in the diagnosis of Alzheimer's disease, as well as in various therapeutic approaches, such as cancer treatment. Accordingly, eight samples with a core–shell structure were synthesized. Throughout the synthesis process, various modifications were implemented to study critical parameters and to produce certain stable, small-sized samples, ideally suited to the objectives of this thesis. Three main techniques were employed for the structural characterization of the samples: X-ray diffraction, scanning electron microscopy, and dynamic light scattering. Subsequently, their magnetic behavior was examined using magnetometry, along with hyperthermia evaluations. In the final stage, correlations were made between the structural, morphological, and magnetic characterization of the nanoparticles, and the most optimal samples were selected.
