Biosensors, constituting cheap and rapid alternate to traditional analytical equipment, have been in the focus of scientific research already for 50 years, since the initial biosensor con‐ cept was proposed in 1962 by Clark and Lyons. Throughout this half century, the number of studies dedicated to the research and applications of biosensor – based techniques is exceed‐ ing 200,000; including those over 14,000 published in 2012.
