Abstract

The synthesis has been made of patterns of single-domain magnetite and related nanocomposites: Fe3O4/dimercaptosuccinic acid, Fe3O4/hydroksylapatite, Fe3O4/γ-aminopropylsiloxane. The influence has been examined of chemical nature of surface of the synthesized nanostructures on the adsorption of cis-dichlorodiamineplatinum complexes. The isotherms and kinetics of adsorption were studied in terms of Pt2+ cations. The best adsorption parameters were observed for Fe3O4/polyacrylamide and Fe3O4/γ?-aminopropylsiloxane nanocomposites. The perspective of using nano-sized magnetite and its modified forms has been shown for the creation of magnetosensitive adsorbents of cis-dichloro-diamineplatinum complexes, in particular, for biomedical applications.

Abstract

Research work results are reviewed related to the problem on directed transport of drugs as well as the current status and prospects in this field. The ways have been analyzed of nanocomposites creation with multilevel hierarchical architecture and functions of biomedical nanorobots such as the capability of microbiological objects recognition in biological media, directed transport and deposition of drugs in target organs, diagnosis and treatment of diseases at the cellular level. Physico-chemical, medical, and biological research data confirm effectiveness of such nanocomposites usage for the creation of new therapeutic forms of combined cytotoxic, immunotherapeutic, hyperthermic effect as well as for neutron capture therapy.

Abstract

Preparation techniques have been developed of magnetic-sensitive nanostructures based on magnetite with incorporated gadolinium ions. Structure and composition of the nanocomposites have been examined by IR-pectroscopy, Xray analysis and X-ray photoelectron spectroscopy. Magnetic characteristics have been studied with vibrating sample magnetometer. An amorphous phase of gadolinium hydroxide has been shown to be formed on surfaces of nanosized magnetite particles. When the samples are heat treated at 800-1000 °?, a crystal phase of ferrite GdFeO3 is formed. [ABSTRACT FROM AUTHOR]
