Magneto-luminescent properties of nanocomposite Fe3O4@SiO2-CdTe in culture medium

Magneto-luminescent nanocomposites can be used as agents for efficient targeted drug delivery. Here, we created a Fe3O4-based magneto-luminescent Fe3O4@SiO2-CdTe quantum dots nanocomposites and studied PL kinetics and magneto-luminescent properties of nanocomposites in biocompatible solvents. We showed that welding a shell of mesoporous SiO2 onto spherical Fe3O4 nanoparticles prevents oxidation of Fe3O4 and saves their magnetic properties.
