1 Introduction
Development of the material science of nanostructures and nanotechnologies alongside with biomedicine makes necessary in the creation of new kind biocompatible
materials that are characterized by relevant physical–chemical properties [1]. Due
to the combination of magnetic, optical, and catalytic properties, the core and shelltype nanocomposites consisted from superparamagnetic iron-bearing particles and
clusters of precious metals on their surface belong to the most suitable structures
for the creation of numerous materials for biology and medicine [2, 3]. At the same
time, gold and silver nanoparticles are in demand to their practical biomedical application due to innative surface plasmonic resonance in a wide frequency range of
exciting irradiation [4], biocompatibility, and selectivity in respect to varies biological substrates, high electro-conductivity, and sorption activity [5–7]. The coating of
magnetic nanoparticles by precious metals, especially gold and silver, leads to their
stabilization in corrosive biological media [8]. Meanwhile, the iron oxide nanoparticles, especially magnetite, doped with metal cations, assume new unique properties
that will provide the enhancing their application field. So, the presence of precious
metal atoms in the magnetite structure may change the physical–chemical properties
of iron oxides. For instance, when aurum was included in magnetite crystal lattice
the magnetic properties of nanocomposite became lower values in comparison to
