Polymeric pharmaceutical nanoparticles preparation: a process optimization
Bárta, Michal ; Holas, Ondřej (advisor) ; Vraníková, Barbora (referee)
Charles University, Faculty of Pharmacy in Hradec Králové Department of: Pharmaceutical Technology Consultant: PharmDr. Ondřej Holas, Ph.D. Student: Michal Bárta Title of Thesis: Preparation of pharmaceutical nanoparticles: optimalization process Pharmaceutical, polymer nanoparticles besides others work as well as a drug carriers. Their uniqueness is not only because of their subcelular size, but as well because of the biodegradability and biocompatibility they hold. The benefit of these nanoparticiples is the possibility of creation of selective naoparticiples which are able to controle long-term release. The formulation of polymer nanoparticles can be reached within methods using preformed polymer or with polymerization of monomers. The main goal of my thesis was to optimize the production process of polymer nanoparticles and the observation of the solvent influences. The methods used for this reaserch were evaporation method and nanoprecipitation. Granulometric and electrical characteristics of particles were measured with Zetasizer ZS 90. Measurements have prooved, that it is preferable to use the nanoparticle method for the prepartion of the the small nanoparticles with low polydispersity and sufficient stability. From the results of the granulometric analysis of nanoparticles made by the...

Biodegradable polymeric nanoparticles preparation
Bacskaiová, Silvia ; Holas, Ondřej (advisor) ; Dittrich, Milan (referee)
Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of: Pharmaceutical technology Consultant: PharmDr. Ondřej Holas, Ph.D. Student: Silvia Bacskaiová Title of Thesis: Biodegradable polymeric nanoparticles preparation The present scientific progress in an important rate conduces to nanomedicine development, which aims to reengineering of cancer pharmacotherapy and other substantial diseases. The main intention of this graduation thesis is the study of surface-active chemical's effects on the final properties of nanoparticles. The theoretical part is focused on the nanoparticles likedrugs vehicles, synthesis of biodegradable nanoparticles, themselves applications in the cancer therapy, diseases accompanied by inflammations, vaccination and for another different purposes. The theoretical part also contents characterization of active and passive goal- directed distribution by diseases, microencapsulations, synthesis of nanoparticles by polymerization and from previously synthesized polymers and definition of physical- chemical properties of nanoparticles. The experimental part is more extensive and concerned with the optimalization of reaction conditions of nanoparticles synthesis, with selection of advisable concentracion and type of surfactant. In the experimental part were...
