The electrotransport, sorption, and photochemical properties of polyoxometalateO 416 H 6 (H 2 O) 58 (CH 3 CO 2 ) 6 ] · xH 2 O (x ~ 250) with a toroidal structure are studied. Con ditions for studying these characteristics are selected on the basis of data on the stability of POM, in depen dence on the concentration and acidity of the medium and the processes of thermal decomposition. A set of independent physical and chemical methods of analysis is used. The possibility of the complexation of toroi dal POM with polymer molecules is established. The photostabilizing effect of this POM on polymer mole cules is revealed.

Nanocluster polyoxometalates with a structure of buckyball (fullerene) are a promising means of targeted delivery of drugs in the body. In this paper, based on an analysis of histological sections of liver and kidney and peripheral blood, showed a significant reduction of toxicity of buckyballs, containing ions of molybdenum (VI), the substitution of Mo (V) ions to Fe (III), in contrast to buckyballs based on Mo (V). The absence of accumulation of molybdenum in rats with a daily intramuscular injection of aqueous solutions of both drugs within a month was confirmed

Abstract-There were no significant deviations from the norm in the functional state of the liver, kidneys, and pancreas in the study of the acute toxicity of iron-molybdenum buckyballs intended for targeted drug deliv ery. No accumulation of nanoparticles or deviation from the norm in any investigated parameter was detected in the study of subacute toxicity.
