• properties of the composites. Nevertheless, a good compromise was achieved in order to maintain the dual modality of the nanocrystals, which may be promising candidates for various biological applications.

• facile synthesis of epitaxial heterocrystalline nanoparticles, consisting of an Fe3O4 shell surrounding a core/shell of Mn-doped ZnS/ZnS QDs. The choice of the Mn:ZnS/ZnS system was motivated by its very low toxicity and thus potential use in various biological applications such as fluorescent labelling

• the preparation of nontoxic bimodal magnetic and luminescent nanocomposite materials consisting of Fe3O4 NPs and Mn-doped ZnS QDs. The synthesis was achieved by depositing a silica shell over Fe3O4 NPs with TEOS. Further, Mn-doped ZnS QDs were bonded with APS activated Fe3O4@SiO2 NPs through
