The aim of the investigations was to evaluate benefits of the directed transport system—a nanocomposite, based on cisplatin and magnetite combined with local action of constant magnetic field on the tumor, in experiments in vivo in animals with transplantable Guerin carcinoma. Animals were divided into 5 groups according to the type of agent. We showed that nanocomposite in combination with sta...

A magnetic chitosan-polypyrrole-magnetite (Cs-PPy-Fe3O4) nanocomposite is prepared in a simple one-step method via in situ chemical polymerization of pyrrole using anhydrous FeCl3 as an oxidant in the presence of Cs. Magnetic Fe3O4 nanoparticles of size in the range of 10-20 nm are successfully introduced into the Cs-PPy matrix. Adsorption of an anionic dye (acid green 25, AG) from aqueous solu...

Nanocomposite microcapsules with both gold and magnetite nanoparticles in the shell were prepared in a layer-by-layer procedure using biocompatible polyelectrolytes and nanoparticles. The process of a nanocomposite multilayer formation was investigated using a quartz crystal microbalance (QCM). In addition, nanocomposite microcapsules were characterized by atomic force microscopy (AFM), transmi...

The nanocomposite magnet, which is composed of exchange coupled nanocrystalline soft (Fe3B, α-Fe) and hard (Nd2Fe14B) magnetic phases, was first reported by Coehoorn et al. [1], and the theoretical basis of it was reported by Kneller and Hawig [2]. Nd-Fe-B based nanocomposite magnet has attracted considerable research interest due to its excellent magnetic properties with relatively low amount ...
