Abstract

Nanoscale multifunctional magnetic materials show unique size, shape, and structure dependent magnetic properties, making them suitable for a range of biomedical applications from magnetic hyperthermia therapy to magnetic actuation, magnetic drug delivery, and magnetic resonance imaging (MRI). The development of ultra-high performance magnetic nanoparticles faces a critical challenge related to the transition from ferromagnetism (multidomain structure) to superparamagnetism (single domain) as the size of materials approaches to the nanoscale. This has become a physical limit to the use of magnetic nanoparticles for practical applications. To address this, I will first discuss recently provisionally patented manufacturing technology to develop ultra-high performance magnetic materials of superior magnetic properties (i.e. the realization of ferromagnetic behavior at the nanoscale). In the second part, I will talk about a simple self-assembly based strategy for designing artificial materials via the assembly of nanoparticles of different sizes and materials and their collective magnetic and mechanical properties. Also, how magnetic interactions within self-assembled micro-and mesoscale materials contribute to the mechanical properties of the self-assembled magnetic materials which have not been explored yet, will be discussed. Understanding the collective properties of self-assembled materials is essential for fabricating intelligent magnetic materials with superior magnetic and mechanical properties for various practical applications from biomedical to energy and information storage. At the end of my presentation, I will provide an overview of my future research vision and directions at GTIIT.
