The group focuses on basic and applied research of promising nanoparticles, especially nanodiamonds, technologies of their preparation, processing, their targeted modification and study of their interfaces, especially by microscopic and spectroscopic methods.
We focus on a comprehensive understanding of the relationships between structure, size, surface chemistry, and colloidal and optoelectronic properties of nanodiamonds with potential applications in biomedical, environmental, and optoelectronic applications. We study optoelectronic phenomena at the interface and physicochemical interactions of nanodiamonds with other materials, e.g. in the form of nanocomposites.
In particular, we use and study surface chemistry modifications by thermal and plasma processes, deaggregation and fractionation.
We are developing microscopic and spectroscopic methods to understand physical states and processes. In specific cases, we develop the methodology and applicability of the methods themselves, taking into account the nature of the materials studied.
