The intention of master thesis' work was to test the cellular uptake and effects of various nanomaterials on two types of cells: human cell line SH-SY5Y and protozoan Tetrahymena thermophila. We were checking whether nanoparticles with bovine serum albumin (BSA) protein corona affects possible cytotoxicity of nanoparticles. We chose three types of TiO2 and one type of CuO nanoparticles at concentrations from 10 to 75 μg/mL. After treating SH-SY5Y with nanoparticles we used three tests to determine cytotoxicity: resazurin assay, neutral red assay and Coomassie brilliant blue assay. In case of Tetrahymena thermophila we used only resazurin assay. To determine cellular uptake of nanoparticles in SH-SY5Y cells neutral red assay was used, whereas light microscopy for Tetrahymena thermophila. Our results revealed that cell line SH-SY5Y is more sensitive to the effects of nanoparticles than T. thermophila. CuO and one type of TiO2 nanoparticles displayed some cytotoxic effects on SH-SY5Y. In most cases protein corona diminished the effect of TiO2 and CuO nanoparticles on SH-SY5Y but did not affect the toxicity on Tetrahymena thermophila. We confirmed cellular uptake of nanoparticles in Tetrahymena thermophila but not in SH-SY5Y.
