Abstract
Rhodium – and iridium-containing films based on the natural polymer of chitosan plasticized with glycerol have been obtained. In this work, a comprehensive analysis of the materials obtained by X-ray phase analysis (XRD), X-ray spectral analysis (XRD), scanning electron microscopy (SEM) was carried out, and the mechanical characteristics and biological properties (antibacterial and antiproliferative activity) of the obtained films were also studied. An analysis of the mechanical properties of the films showed that iridium-containing samples are character- ized by higher mechanical properties than rhodium-containing samples. Thus, we can conclude that the nature of the metal center affects the mechanical properties of the films. Iridium films have greater antibacterial activity than the corresponding rhodium films. The antiproliferative activity of the studied samples is due to the content of rhodium
(III) and iridium (IV) and is practically independent of the nature of the introduced metal cations.
