A Study Of Fe3O4 Magnetic Nanoparticle Rf Heating In Gellan Gum Polymer Under Various Experimental Conditions For Potential Application In Drug Delivery, Gabriel Marcus
USF Tampa Graduate Theses and Dissertations
Magnetic nanoparticles (MNPs) have found use in a wide variety of biomedical applications including hyperthermia, imaging and drug delivery. Certain physical properties, such as the ability to generate heat in response to an alternating magnetic field, make these structures ideal for such purposes. This study's objective was to elucidate the mechanisms primarily responsible for RF MNP heating and determine how such processes affect polymer solutions that might be useful in drug delivery. 15-20 nm magnetite (Fe3O4) nanoparticles at 0.2% and 0.5% concentrations were heated with RF fields of different strengths (200 Oe, 400 Oe and 600 …
