Željka Boček is a teaching and research assistant at FCET, where she is currently pursuing her PhD. The topic of her doctoral research is Novel printed electrochemical (bio)sensing systems for point-of-need analysis. She has experience in electroanalytical chemistry and development and characterization of printed electrochemical sensors. She will be involved in all activities related to electrochemical processing and characterization (WP1), with smaller roles in direct voltammetric sensing (WP2) and CRISPR-Cas biosensing (WP4).

Zvonimir Katančić is Associate Professor at the Department of Polymer Engineering and Organic Chemical Technology, FCET. He is a recognized researcher in the field of materials science, specializing in the development and characterization of polymers and polymer (nano)composites. His expertise in inkjet printing and materials characterization will be leveraged mostly in WP1, with smaller contributions in WP2 and WP3 (applications).

The FCET team is complemented by international experts in their respective fields

Jacek Ryl is a Professor at the Gdańsk University of Technology, where he is Head of the Division of Electrochemistry and Surface Physical Chemistry at the Institute of Nanotechnology and Materials Engineering. The principal area of his scientific activity lies in applied electrochemistry, electrochemical sensors, and materials science. He is an expert in sustainable additive manufacturing of electrochemical sensors so he will oversee all 3D printing of electrodes (WP1), with minor roles in activities related to their application (WP 2-4). He is an expert in XPS analysis so he will perform this characterization of all electrodes (WP1) and provide training to junior researchers from FCET. 

Daniel Citterio is a Professor of analytical chemistry at Keio University, Yokohama, Japan. He has published over 200 papers and has over 15 years of experience in the development of low-cost paper-based analytical devices targeting clinical diagnostics. Most recently, he has been working on paper-based CRISPR-Cas biosensors. He will contribute his expertise mostly in WP4 for CRISPR-Cas electrochemical sensor development, as well as provide short training on this topic to researchers from FCET, with minor contributions in WP1.

IBP CAS - Institute of Biophysics of the Czech Academy of Sciences Team

Co-PI, Stanislav Hasoň is a recognized researcher specializing in electrochemical analysis of biomolecules at charged nanostructured carbon-based interfaces. Recently, his research has focused on GO-modified electrodes for biosensing applications in real biological matrices.  As co-PI, he will oversee experimental work and coordinate scientific activities at  IBP CAS.  His experimental responsibilities include: (i) preparation and characterization of GO-PCEs (WP1); (ii) Voltammetric and impedimetric detection at GO-PCEs (WP2); validation of developed sensors in biological samples in WP3 and WP4.

Veronika Ostatná is a recognized researcher in protein electrochemistry and has co-authored over 90 JCR articles. As a senior researcher and team member, she will primarily contribute her expertise to WP2, focusing on direct electrochemical analysis of biomedically important molecules. She will provide training for junior researchers and will participate in scientific paper preparation.

Lukáš Fojt is a recognized researcher in the fields of electrochemistry of boron cluster compounds, impedimetric analysis of nucleic acids and their analogs at charged electrode interfaces, and AFM analysis of biomolecules on electrode surfaces. He is a co-author of 35 articles in JCR. In WP1, he will lead the impedimetric, AFM, and Raman characterization of GO-PCEs. In WP2, he will oversee the impedimetric detection of low- and high-MW molecules. In WP4, he will direct the optimization of covalent ssDNA immobilization on GO-PCEs.

Lukáš Zámečník is a Ph.D. student of Brno University of Technology,Czech Republic starting his PhD study in September 2026. He will learn and master the electrochemical and analytical methods used by the team to contribute to the project goals in WP1 and WP2.
