Abstract. Over the last two decades nanotechnology has become one of the most dynamically evolving field of research. The unique properties of nanomaterials, not disclosing at microscale, are examined and exploited to extend our understanding of the interactions taking place at atomic or molecular level. Those findings affect research in many areas, like e.g. alternative energy sources, electronics, physics and medicine. In this paper, the possibility of using nanomaterials for the enhancement of photodynamic activity, is discussed. A brief review on drug-delivery facilitating nanomaterials, regarding their characteristic features, is presented. An exemplary application of silver-doped nanomaterials for enhancement of photodynamic properties of two photosensitizers: Photolon and Protoporphyrin IX, is described. Influence of silver-doped nanomaterials addition on the fluorescence intensity of photosensitizers immobilized in silica-titania (SiO2-TiO2) sol was examined via VIS spectroscopy. Influence of sonication on the fluorescence enhancement was also investigated. It was demonstrated that the fluorescence enhancement of photosensitizers depends on the concentration of both: photosensitizer and silver-doped nanoparticles.

In this investigation radical induced copolymerization reaction of vinylpyridine (VP)‐Thorium (Th(IV)) complex with pure methylmethacrylate in dimethylsulfoxide using azobisisobutyronitrile as initiator led to formation of polymer metal composite. The prepared polymer composite was characterized by elemental analysis, Fourier transform infrared (FT‐IR) spectroscopy, thermogravimetric analysis, scanning electron microscopy (SEM), transmission electron microscope and X‐ray diffraction. FT‐IR results showed that the metal ion is coordinated via the nitrogen of VP. The solubility of Th(IV) complex and the formed polymer composite in polar and non‐polar solvents was also tested. However, the conductivity measurements revealed nonelectrolytic nature of the complex. Moreover, the thermal properties of the prepared composite and their antitumor and antimicrobial activities were discussed. Additionally, in this work not only the nanocomposite as bulky materials (powder) but thin films also were deposited utilizing electrospray deposition technique. The produced films have been reduced growth of gram‐negative Escherichia coli by ∼99.1%. The morphology of the prepared film was studied by SEM and atomic force microscopy. POLYM.

“…A number of processing techniques have been carried out to decorate or incorporate TiO 2 NPs in/on polymeric matrices such as solegel and sputter coating [9], layer-by-layer assembly [10], and electrospray deposition [11]. For the deposition of Ag NPs, techniques such as in-situ decoration [12], chemical reduction of AgNO 3 precursor [13], and controlled assembly [14] have been widely studied.…”
