Topic of the lecture
Magnetic nanoparticles are fundamental building blocks in a wide range of applications, including dense data storage, spintronics and nanomedicine. The functional performance of these nanoparticles is largely determined by their magnetic anisotropy, which results from the surface properties, shape and interfacial interactions in hybrid structures. In this talk, I will present key aspects of effective magnetic anisotropy and methods for its design for a variety of applications.
Optimisation in biomedical applications
Tuning magnetic anisotropy is crucial for optimising the performance of nanoparticles in biomedicine, particularly for enhancing contrast in MRI imaging and improving the effectiveness of magnetic hyperthermia in cancer therapy. A significant challenge in this field is the need to:
- improve surface functionalization,
- increase the specific absorption rate (SAR) or heating efficiency of nanoparticles for more effective cancer diagnosis and treatment.
Modern structural strategies
To address these challenges, strategies beyond conventional spherical nanoparticles, such as exchange-conjugated core-shell structures, nanowires and nanotubes, offer promising paths to enhance saturation magnetization, effective anisotropy and thermal performance in magnetic hyperthermia.
