Functionalization of cerium oxide nanoparticles by simple biomolecules

In this diploma thesis we propose to study nanoparticles of cerium dioxide with a size of a few nanometers functionalized by simpler biomolecules, such as histidine or glycine, from solution. The nanoparticles will be characterized by microscopic methods (AFM, SEM, TEM), dynamic light scattering (DLS) and UV-vis spectrometer. The focus will be on the study of the nature of bonds formed between biomolecules and CeO2 nanoparticles by photoelectron spectroscopy using synchrotron radiation (SRPES, RPES, NEXAFS) and XPS. The research will be carried out in collaboration with Dr. A. Shcherbakova and Dr. N. Zholobakova, Zabolotny Institute of Microbiology and Virology, National Academy of Sciences of Ukraine. The photoemission experiments will be carried out mainly at the Materials Science Beamline (MSB) at the Elettra synchrotron in Trieste. The aim of this work will be to study the way biomolecules interact with the surface of cerium dioxide nanoparticles.
