The nanocluster polyoxometalate Mo72Fe30 is interesting as nanocapsule for targeted delivery of drugs in the body. In solution Mo72Fe30 is charged, which creates the possibility of its introduction by electrophoresis. In this work the electrophoretic transfer of its associates with biocompatible polymer - polyvinylpyrrolidone, which is necessary to «disguise» nanocluster from the reaction of the immune system, and cations of lanthanum, which can be used as ion tags to monitor the movement of nanocluster in the tissues of the body was made. We calculated the coefficient of diffusion of associates.
