Presented diploma thesis deals with drug encapsulation of Sulfathiazole (STA) in thermosensitive hydrogel composed of amphiphilic fibrous molecules of copolymer poly(D,L-lactide-co-glycolide)-block-poly(ethylene glycol)-block-poly(D,L-lactide-co-glycolide) (PLGA-PEG-PLGA). In the experimental part, the structure of the micelles which is dependent on the concentration of the default copolymer, was thoroughly described. The method of dynamic light scattering (DLS) was used to dimensionally characterize the micellar size in aqueous solution. At the same time, the Cryo-Transmission Electron Microscopy (Cryo-TEM) imaging technique confirmed the transition from spherical micelles to fibrous branched structures with a number of topological interactions. The change in viscoelastic properties of micellar hydrogel after addition of STA was studied by rheological analysis. The studied triblock copolymer appears to be a suitable tissue engineering material as a carrier in applications for targeted drug delivery and tissue regeneration.
