The 37th Seminar of Advanced Materials Center | Gdańsk University of Technology

We warmly invite you to the 37th seminar of the Advanced Materials Center, which will take place on February 19th, 2026 (Thursday) at 1:15 p.m. in EA Auditorium 1 (building 41, ETI A).

Prof. Petar Kassal, leader of the PrintEChemSens research group at the University of Zagreb, Croatia, will present a talk entitled "Contactless printing technologies in the development of flexible electrochemical (bio)sensors".

Prof. Kassal’s research group (https://www.fkit.unizg.hr/PrintEChemSens) has deep experience in printed electronics and electrochemical sensors, including formulating conductive nanoparticle- and carbon-based inks and manufacturing low-cost, scalable sensors on flexible substrates. Their expertise with wearable chemical sensing and environmental electroanalysis, along with emerging approaches such as photonic sintering and integrated Lab-on-a-Chip platforms.

After the seminar, we traditionally invite you for pizza!

Abstract:

Employing established technologies from the printed electronics industry can enable high throughput and cost-effective fabrication of flexible electrochemical sensing devices, thus achieving distributed (bio)chemical sensing. In our research, we focus mostly on inkjet printing - a highly versatile, scalable and low-cost fabrication technology - coupled with intense pulsed light (IPL), which enables split-second photothermal processing of the inkjet printed features. In this seminar, we will discuss our approach to synthesis of inkjet-printable conductive inks (nanosilver and graphene based) and the effect of IPL on morphological, electrical, and electrochemical properties of the printed inks. Examples will be given of developed flexible (bio)chemical sensors including ion-selective and reference electrodes, voltammetric sensors for pharmaceuticals, wearable lactate bio sensors and artificial lung systems with integrated pH sensing.
