Preparation and characterization of IONPs–QDs. (A) Schematic representation of IONPs conjugated with QDs. IONPs (with carboxylic acid groups) conjugated with QDs (with amine groups) using the EDC–NHS method, as a mode of stable tracking in cells. (B) Transmission electron microscopy (TEM) image of IONPs–QDs at different scales (100 and 25 nm). (C) Magnetization loops of IONPs–QDs.
