A Brief Story of Biosensor Technology

The vast literature in the last 40 years related to the keyword Biosensor reveals tvithout doubt that the scientific field is attractive We realized at once that several researchers with different bacl round ate involved in this field of research, from chemistry to physics, to microbiology and of course to elearical engineering, all are deeply involved in several facets of the assembly of the object Biosensor . 

Looking at the past we realize also that the concept of Biosensor has evolved  

Starting from 1970, several others authors start to prove the concept of Biosensors, the coupling of an enzyme and electrochemical sensors. This was at the beginning a Biosensor, a strange research where biological elements were combined with electrochemical sensors. 

In the electrochemical community at that period the research on ion selective electrodes (ISE) was very active and the idea to extend the range of sensors to non electrochemical active compounds, and even to non ionic compounds, like glucose, has been very well accepted. We saw at that time the possibility to extend much more the research activity. The groups active in ISE development have been definitively the first to shift to the development of electroanalytical biosensors.
