Immobilization in polyvinyl alcohol decreases specific absorption rate (SAR) of multicore MNP fluidMAG-D by a factor of two. SAR values of multicore MNP in water suspension and immobilized in 1% agar and 10% PVA. Additionally, hydrodynamic diameters (Øhydr.) for each MNP type are shown. Values in brackets indicate core size determined by TEM micrographs. Error bars indicate standard deviation of three independent measurements. fluidMAG-D coated with starch (A) and starch-coated 100-nm fluidMAG-D MNP with differently clustered cores (B).
