Course detail

Electronics and Biosensors

FEKT-MPA-BSNAcad. year: 2023/2024

The concept of the course is focused on the fundamental aspects of biosensors and electronic biochips. Students will gain an overview of biosensors, especially of electrochemical, optical, piezoelectric and calorimetric type. They will get knowlegde about biocatalytic (enzymes) and bioaffinity (antigen-antibody, DNA or biomimetic) biosensors and their application in medicine, environment and food area. A part of the course will be devoted to the sensor technology (lithography, miniaturization, microfluidics) and nanomaterial (nanoparticles, nanowires) application in biosensing.
