We study magnetic nanoparticles and their applications. Using physical and chemical fabrication techniques, we designunique nanoparticle systems to understand how disorder affects magnetic properties, and how nanoparticles can be used for biomedical applications such as drug delivery, magnetic resonance imaging contrast, and hyperthermia.
We make nanoparticles using a variety of methods. Each method is chosen for the physical and chemical characteristics that result. Our primary technique is inert gas condensation, which uses a thermal gradient to produce nanoparticles
Ferromagnetic and antiferromagnets are interesting, but we're interested in what happens when the magnets are disordered on an atomic basis. Disruptions from periodicity can have big effects on magnetic behavior.
Our nanoparticles are being investigated for applications in magnetic resonance imaging contrast and drug delivery. We are developing new types of biocompatible nanoparticles that will have multifunctional behavior.
