Abstract
A method is presented for producing nanosized oxide ferromagnetics from salt systems with the use of the mechanochemical activation and their fundamental properties are investigated. Results concerning the use of the oxide ferrimagnetics synthesized for the magnetofection of DNA, DNA/RNA sorption, microbial cells, proteins, and contrast agents for MRT diagnostics are reported. It has been found that nanoparticles are non-toxic; their distribution in internal organs and the decrease dynamics, the possibility of using them for medication transport have been demonstrated.
