(369d) Development of Magnetic Nanoparticles and Nanocomposites for Environmental and Biomedical Applications

Magnetic nanoparticles (MNPs) and their nanocomposites can provide unique solutions to environmental and biomedical problems. The magnetic nanoparticles enable for energy to be delivered remotely to the material using an alternating magnetic field (AMF). This localized energy can be used to drive processes to enhance material performance, including disruption of binding interactions, increased reactivity, manipulation of biological systems and assemblies, etc. Here, we will highlight a few diverse applications (e.g., low energy sorbent regeneration, enhanced reactivity, virus inactivation, etc.). For example, decades of use of halogenated chemicals in product manufacturing and commercial applications have been connected to detrimental health impacts. In response to these, we have applied magnetic nanocomposite for the reversible capture of halogenated contaminants such as perfluoroalkyl substances (PFAS) by regenerating the nanocomposite through an AMF.
