AB  - The paper presents chemical and structural analysis of geopolymer materials which are obtained by alkali-activated calcined clay (metakaolin) originated from Serbia under strictly defined conditions. Characterization of the metakaolin and geopolymers molecular structure has been done using X-ray diffraction, scanning electron microscope, Fourier transform infrared spectroscopy and matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The paper presents the possibility of obtaining geopolymer structure and differences in chemical and structural characterization of these materials taking into account the concentration of NaOH as a variable parameter. The results of MALDI analysis of metakaolin and synthesized geopolymer structures using various matrix system: 2,4,6 trihydroxyacetophenone (THAP), alpha-cyano-4-hydroxycinnamic, 2,6 dihydroxyacetophenone and laser desorption/ionization, have shown that THAP matrix is the most appropriate for analysing these aluminosilicate materials.

AB  - We studied the colloidal TiO2 nanoparticles as a carrier for controlled delivery of the ruthenium complex to the melanoma cell line. The system demonstrated slower complex release upon visible and increased release rate upon UV light illumination. Accordingly, the light-dependent cytotoxicity of the system was demonstrated on amelanotic melanoma cancer line. The cell death is enhanced by UV and reduced by red light in the presence of investigated nanocomposite system. Both components of the system may act as photosensitizers, by generating reactive oxygen species, which promote cell death. Thus, the system might act dually, as photodynamic therapeutic agent and as the light tunable system for metallo-drug delivery and it might be of interest for development of new more efficient drug delivery approaches by using a light as external stimulus.
