Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of: Pharmaceutical Technology Consultants: PharmDr. Ondřej Holas, Ph.D. Student: Simona Žemličková Title of thesis: Hybrid polymeric-lipid nanoparticles as drug carriers The work is focused on hybrid polymer-lipid nanoparticles, their advantages obtained from polymer and lipid part, purpose of surface modification, basic properties of nanoparticles, methods of preparation, modification of preparation conditions and use of nanoparticles in medicine. The aim of the experimental part was to prepare nanoparticles composed of polyester and lipid by emulsion evaporation method and nanoprecipitation. Two types of linear polymer poly (lactic-co-glycolic acid) and phosphatidylcholine were used in various ratios. The surfactant used for stabilization was poloxamer Pluronic® F127 and the organic solvents were ethyl acetate and acetone. Curcumin served as a model active substance. The effect of lipid and surfactant on the size and zeta potential of nanoparticles was evaluated. Modification of preparation conditions, which included many process parameters, also influenced the monitored parameters. Encapsulation effectivity and drug loading were also tested. Dissolution tests were performed. It was found that size of nanoparticles...
