Due to their large specific surface, the nano and mesoporous silica gels have special adsorption properties, thus they are emerging candidates for controlled delivery of bioactive materials like drugs or adsorption of poisonous materials. To synthesize such silica gels, the accurate description of the interactions between the silica matrix and – mostly water based – solutions is needed. The main target of our research is to describe and understand the relationship between the structure of the silica gels synthesized with different substituents and the solution of biologically active molecules, and, based on the results, synthesizing of organically modified silica gels used as support for controlled drug delivery.
The role of the PhD candidate is to perform elastic, quasielastic and inelastic neutron scattering measurements to reveal the static and dynamic structure of the system composed of silica gel and solution of bioactive materials, comparing the results with other kind of measurements (like NMR), and giving complex description of the interaction of the modified silica gels and the bioactive materials. During his work the PhD candidate has to take part in the design and development of the neutron scattering instruments at the Budapest Research Reactor as well.
