Pokročilé mikroreologické techniky ve výzkumu hydrogelů / Advanced microrheological techniques in the research of hydrogels

This diploma thesis deals with the use of fluorescence correlation spectroscopy technique for microrheological characterization of hydrogel in a system of hyaluronate-cetyltrimethylammonium bromide. Fluorescently labelled particles were used for microrheological FCS analysis. To optimize the method the most appropriate size of particles was chosen on the basis of Newtonian glycerol solutions analysis. Among other things, the discussion was focused on the influence of refractive index change of analysed solutions on analysis results. After hyaluronate solutions analysis it was possible to assess the biopolymer concentration and molecular weight impact on the FCS microrheology results, which could then be compared with analysis results of model hydrogels of hyaluronate and CTAB. Finally, usability and limitations of FCS microrheology have been discussed.
