DoP Colloquium - Vedran Đerek

Bioelectronics: from materials science and micro-fabrication to biophysics
(Vedran Đerek - Department of Physics, PMF, Zagreb)

This seminar will present an interdisciplinary approach to bioelectronics – bridging materials physics and microfabrication technologies with the biophysical mechanisms that govern the operation of electronic interfaces in biological systems. The first part will focus on the physics of materials: the selection of electrically and ionically conductive, as well as biocompatible materials, their micro- and nanostructure, and how these properties influence their electrical, optical, and mechanical behavior. Special attention will be given to the use of organic conductors and semiconductors in bioelectronic devices. The second part will cover advanced microfabrication methods, including femtosecond laser processing, which enable the realization of precise structures such as microelectrodes, sensors, and transistors for controlled communication between electronic systems and biological environments. The final part will address the biophysical aspects – the transfer of electrical and ionic signals, interface stability and compatibility, and models describing their behavior. The seminar will provide an overview of the fundamental physical principles linking materials physics, semiconductor physics, microfabrication, and biophysics into a unified framework for the development of bioelectronic devices – from sensors and stimulators to implantable systems.
