The 40th Seminar of Advanced Materials Center | Gdańsk University of Technology

We warmly invite you to the 40th seminar of the Advanced Materials Center, which will take place on April 8th, 2026 (Wednesday) at 1:15 p.m. in NE 140 (building 42, WETI B).

Prof. Larysa Baraban, leader of the Nano-Microsystems for Life Sciences research group at the Technical University Dresden, Germany, will present a talk entitled "Nano and micro devices for clinical diagnostics".

Prof. Larysa Baraban is Professor of Medical Nanotechnology, an ERC Consolidator grantee, and the head of the department 'Nano-Microsystems for Life Sciences' at Helmholtz Zentrum Dresden-Rossendorf (HZDR) in Germany. Her background includes research across multiple areas of materials science, microsystems, and biotechnology, including bionanosensing integrated into microfluidic systems and novel, artificially designed micro- and nanodevices.

After the seminar, we traditionally invite you for pizza!

Abstract:

Novel strategies for on-chip integrated nanoelectronic devices inspired the development of a new generation of biosensors, employing inorganic and organic materials. The main element of such biosensors is the semiconductor (e.g. in field effect transistors) or metal (in electrochemical, chemiresistive or impedimetric sensors) transducer, with the radically miniaturized sensing area down to the several nanometers. Merging such nanodevices with the biological species, e.g. cells or molecules of similar nanosizes, offers the remarkable increase in the biosensor sensitivity. When combined with microfluidic technology this approach relies on the measurement of the electrical response of the device, such as current, voltage, or electrical impedance for monitoring of low titration levels (down to femtomolar levels) of diverse biomolecules in physiological fluids. Despite this success, the nanobioelectronics is still underrepresented in the field of oncology. While the research area has addressed their potential applications in early cancer diagnosis, less efforts have been dedicated to the therapy development and patients monitoring. In this area potential use cases are mostly limited by the liquid biopsy, detection of circulating tumor cells or circulating tumor DNA. Here we review some of the important contributions to the field of nanobioelectronics, when applying it to the cancer research. In particular, the implementation of so-called silicon nanowire based field effect platforms, and extended gate systemsfor an ultrasensitive detection of the cancer related biomarkers and cancer related therapy will be discussed.
