Carbon nanostructures, biomacromolecules and simulations

Head of the Division:

Prof. Michal Otyepka, Ph.D.

 About the group:

Graphene and its derivatives (fluorographene, graphene oxide) belong to extensively studied compounds within the framework of our research. The research includes the development of novel methods for the functionalization and chemical modification of graphene and its derivatives. We benefit from a tight connection between both theoretical and experimental approaches. Other research directions include explorations of fluorescent carbon quantum dots and their application for cell imaging, along with the study of porous carbon nanostructures for environmental and catalytic applications. The group develops theoretical methods and tools for the study of biomacromolecules and nanomaterials. The focus is on the structure and dynamics of biomacromolecules and their functional components, on the interaction of biomacromolecules with membrane bilayers, on enzyme and RNA catalysis.

Assoc. Prof. Michael A. Karakassides (Home institution: University of Ioannina, Department of Materials Science & Engineering, Greece) Biomaterials, Hybrids and Mesoporous Materials Group group (group is led by Assoc. Prof. Michael A. Karakassides) was established in 2001 and currently gathers more than 15 researchers, including post-graduate students. It aims at a variety of topics in inorganic porous and hybrids solids, ceramics and glasses and nanomaterials, either in pure or in composite form. Advance applications, such as, biomaterials, carbon nanotubes, graphene, nanocomposites, and traditional ones, such as clay materials, vitrification and ceramization processing of industrially produced ceramics, water cleaning processing with the aid of hybrid nano-ceramic etc., are both included in the activities of BHMM group. High-importance objectives of the group, are the design and the development of new functional materials, including synthesis and processing optimization and characterization up to commercialization level.
