Carbon Bionanotechnology Lab

The research of the Carbon Nanobiotechnology laboratory focuses on the development of functional carbon-based interfaces with enhanced performance in the field of biosensing and diagnostics. Carbon nanotubes (CNTs) and graphene (G) are having a tremendous impact in biosensor design and preparation, in particular as electron transducers in electrochemical devices. In practice, CNT- or G-based interfaces lead to electrodes with large surface areas, which enhance the surface loading of desired biomolecules and increase the sensitivity. In addition, the surfaces possess excellent conductivities with small band gaps, which are beneficial for transferring electrons between the biomolecules and the electrode surface. Besides, the possibility of covalent or non-covalent functionalization of these carbon forms allows for the fine-tuning of the materials intrinsic chemical and physical properties along with the attachment of different recognition motifs (e.g. antibodies or genetic material) or other functional materials. All these properties enhance exponentially the fields of action of the modified electrodes, ranging from the highly sensitive detection of cancer cells to the adsorption of enzymes for improved catalysis. The group also carries out basic research, studying a wide variety of methodologies for functionalization of carbon-based materials (GBMs), such as supported unsupported graphene, reduced graphene oxide or CNTs, mainly based on new cycloaddition and radical reactions. Of interest is also the preparation of multifunctional GBMs for broader applications, such as the design and preparation of new molecular materials with useful optical, electronic and/or biomedical properties.
