Characterization of the MCNPs. A) HR-TEM image of the MCNPs. B) Higher magnification HR-TEM image of the MCNPs shows that the pores are about 3 nm in size. C) Size was determined using TEM and dynamic light scattering (DLS). Moreover, the Zeta potential was confirmed. The values in the chart are given as mean ± standard deviation. D) The MCNPs (25 µg/mL) can be heated to temperatures as high as 47°C after exposure to an alternating magnetic field (5 kA/m, 225 kHz) for one hour.
