The thesis is focused on the research of stability of controlled drug release systems based on a blend of plasticized starch/polycaprolactone (TPS/PCL) that served as a carrier. Antibiotic vancomycin was used as a model drug, and its release from TPS/PCL pellets into aqueous environment was followed by UV-spectroscopy and the obtained time dependences were treated by a simple kinetic model. Moreover, the simultaneous release of starch particles to the surrounding liquid phase was studied by static and dynamic light scattering as well as transmission electron microscopy (TEM) in order to obtain information on the stability of biodegradable matrix and on the structure of the products of the pellet decomposition on a nanoscale level. Key words: vancomycin, starch, drug delivery system, polycaprolactone (PCL), particle release, dynamic light scattering (DLS), static light scattering (SLS)
