Anastasios Papavasileiou obtained his B.Sc. (2018) and M.Sc. (2020) in chemistry from the University of Ioannina in Greece, specializing in electrochemical sensing. Subsequently, as a research intern he visited Masaryk University in Brno, Czech Republic through the European mobility program, Erasmus+. Currently, he is a doctoral student at the University of Chemistry and Technology (UCT) in Prague, accompanied by two scholarships. He has co-authored 8 publications and received Emil Votoček award for ranking among the top 20 PhD students at UCT for the academic year 2023/2024. His main research interest lies in applied electrochemistry and sensing utilizing advanced technologies and novel materials, with a keen interest in 2D materials, magnetism, and 3D printing technology.

Talk Title: Unfolding the potential of electrochemically activated 3D printed electrodes as sensing platforms

Commercial conductive filaments are not optimized for electrochemical applications, leading to 3D-printed electrodes with limited exposed conductive surfaces and poor electrochemical performance. Selecting an appropriate activation method is essential to unlock their full potential for their implementation in advanced applications. In this work, we propose electrochemical activation as a sustainable, time-efficient, and highly reproducible method to enhance the electrochemical performance of 3D-printed electrodes fabricated from Carbon Black–Polylactic Acid (CB/PLA). The CB/PLA 3D-printed electrodes are characterized electrochemically, structurally, and morphologically, and evaluated as platforms for electrochemical sensing. Moreover, the 3D printed electrodes are utilized as counter, working and pseudo-reference electrodes as part of a fully 3D printed electrochemical cell that will allow the on-site electrochemical analysis.
