Heating behavior of uncoated and lipid-coated SPIONs within an alternating magnetic field. Uncoated (open symbols) and lipid-coated (closed symbols) Fe3O4 nanoparticles suspended at 0.02 mg/mL in citrate buffer, pH 7.4, were exposed in the MGS-1000 to an alternating magnetic field of 7.0 mT at 1.0 MHz (circles) and in the MHS to 16.6 mT at 13.6 MHz (squares). Temperature of suspension vehicle was recorded using an optical fiber probe. Data are shown as mean ± SD (n = 3).
