Their capability to encapsulate both hydrophilic and lipophilic molecules, biocompatibility and biodegradability of lipids make them a suitable alternative for well-established drug carries. The aim of this thesis was to determine suitable ratios of composition of nanoparticles with acceptable properties (especially reduced size and polydispersity, high zeta potential absolute values), to investigate status and thermodynamic behaviour of the nanoparticles and lipids used and to examine drug encapsulation efficiency. Nanoprecipitation method was used to prepare nanoparticles from stearic acid as a solid lipid and in the case of NLC preparation isopropyl myristate as a liquid lipid was used. Kolliphor® P 188 as a surfactant and Span® 20 as a co-surfactant were the best choice to meet intended characteristics. It was shown that usually lower the concentration of surfactant and co-surfactant was the...
