Functional nanoprobes for MRI and other bio-applications developed using Fast-Field Cycling NMR

In recent years the development of magnetic iron-oxide nanoparticles (MNPs) for biomedical applications has progressed significantly [1]. A particular focus is on preparing materials with multiple responses, typically any two from MRI image contrast generation, AC-field induced local heating (hyperthermia) and magnetophoretic capture. In this talk some recent work from our laboratory will be presented on the synthesis, surface modification, colloidal stabilization and in vivo use/fate of MNPs, using examples from studies on magnetic nanosphere [2] nanocube [3] and nanoflower [4] suspensions and, time-permitting, on magnetic hydrogels [5]. The use of fast-field cycling NMR relaxometry to study magnetic ordering in suspension, in which the 1H nuclei of the H2O are used as a spy will be described [3]. The moment dynamics is found to determine the hyperthermic and MRI responses in the biological environment [4], and how these functions evolve over time [6]. 1. T. H. Shin, Y. Choi, J. Cheon.
