Confirmation of CMD-coated particles and determination of magnetic strength of SPION synthesized under continuous flow. (A) Weight loss curve [%] obtained for bare SPION (black) and CMD-coated SPION (red) by TGA at a temperature of up to 800 °C. Several steps of weight loss were seen ranging from the release of absorbed water and the first/second CMD decompositions to the oxidation of magnetite to maghemite. The first and second decomposition steps indicate that CMD was splitted from the particle surfaces. (B) Magnetization (M) trend as a function of magnetic field strength (H) measured using a SQUID magnetometer showed highest M-value for bare SPION (black), followed by Resovist (orange), and lowest for CMD-coated SPION (green). Note: magnetization curves were not normalized to magnetic material.
