Characterization of FMNPs. (a) Ternary phase diagram of W/O reverse micro-emulsion reaction system; (b) SEM image of FMNPs, FMNPs were sphere with 150 nm in diameter; (c) TEM image exhibited that the FMNPs are mono-dispersed, silica shells covered Fe3O4/PS and QDs; and (d) the magnified image of the FMNPs presented a silica-shell thickness of 30 nm on average, and the mean total diameter was 150 nm.
