Study of interactions of biomaterials with human cell cultures.
 Maslonková, Ivana ; Kostovová, Iveta (referee) ; Márová, Ivana (advisor)
The bachelor thesis was focused on introducing of techniques of cultivation of human cells in vitro and optimization of their uses in variety of cytotoxicity tests. Further, in this work were studied also interactions of cells with biomaterials and prepared organic-inorganic nanoparticles. In the theoretical part the basic conditions of cell cultivation, the characteristics of keratinocytes as cell cultures, basic characteristics of particles and also short search about the most used tests of cytotoxicity on various cells systems were described. The experimental part was focused on the optimizing the preparation of silver particles, where maltose was chosen as the most appropriate reduction agent. The average size of these prepared particles was 35 nm. The possibility of preparation of combined organic-inorganic particles including liposome particles, PHB particles, alginate particles and chitosan particles was also tested in the thesis. Later, the silver nanoparticles were encapsulated into these organic-inorganic particles as an inorganic component. The liposome particles prepared by ultrasound were evaluated as the most stable of all the other prepared particles. Human keratinocytes were chosen as the cell cultures that were needed for the observation of the particle interactions with human cells. In this work basic methods of cell cultivation and passage were introduced. Conditions of experimental work in cell culture laboratory were setting and possible application of cell cultures to cytotoxicity testing by MTT was tested.
