AMF induced magnetic nanoparticle hyperthermia in alginate microcapsules containing magnetic iron (III) oxide. Engineered E. coli were co-encapsulated with iron oxide nanoparticles in alginate microcapsules (a). The tube containing the microcapsules was placed in a brass coil, and three optical fiber probes were placed in the tube to record the temperature. The microcapsule suspension was exposed to a magnetic field of 450 Oe until the temperature reached 43 °C, at which point the field strength was reduced so as to maintain the desired temperature (b).
