Jan Tkac received his Ph.D. degree in biotechnology at the Slovak University of Technology (Bratislava, Slovakia) in 2000. He received his postdoctoral appointment at the Linkoping University (2001-2003), Lund University (2003-2006) and Oxford University (2006-2008). Currently, he works at the Institute of Chemistry, Slovak Academy of Sciences in Bratislava. He was/is a recipient of an Individual Marie Curie Fellowship (2003) and an ERC Starting grant (2012). His main research activities cover a microarray platform of detection of glycoproteins by lectins with the aid of nanotechnology. He has published 80+ scientific articles, reviews, and 4 book chapters having 1000+ citations.


Integration of nanotechnology into the field of glycomics can address current limitations of fluorescent glycan and lectin microarrays [1,2]. Moreover, label-free transducing schemes especially when working in an ultrasensitive fashion can be applied in a reliable detection of low abundant disease biomarkers [3-5]. For example, electrochemical impedance spectroscopy applied in our studies allows to detect analyte molecules down to a single molecule level (i.e. aM level) if immobilization architecture of ligands (lectins or glycans) is controlled at nanoscale [6-8]. Utilization of such devices in serological glycoprofile of samples from people having some diseases, in analysis of cancer biomarkers, cancer cell lines and viruses will be discussed.
