Annotation	Mn-Zn ferrite nanoparticles of the composition Mn0.61Zn0.42Fe1.97O4 and mean size of crystallites dXRD = 11 nm are synthesized under hydrothermal conditions as a single-phase product. Two coated samples are prepared by encapsulation of the ferrite particles into silica and titania. Magnetic measurements on bare and coated particles show high magnetization of the cores and superparamagnetic state at room temperature. The relaxometric study on aqueous suspensions in magnetic fields of 0.5 T and 11.75 T reveals high transverse relaxivity of the samples. Careful evaluation of cytotoxicity of coated particles is carried out by using the determination of viability and proliferation of Jurkat cells and the real-time monitoring of attachment and proliferation of A549 cells. In the studied range of concentrations, the viability and proliferation of suspension cells are not affected at all.
