Title: Design and production of an amperometric biosensor Multi-parameters

Abstract:

In general terms, a biosensor is considered to be a detection device that combines several technologies such as molecular biology, microelectronics, automation and computer science. It combines a biological element (antibody, enzyme, lipids, plant or animal cell, DNA fragment, etc.) with a physical transducer (optical fiber, electrode, piezoelectric quartz, etc.). This association allows the study of substances likely to interact with the biological element.

 Biological sensors have undergone considerable development due to their simplicity, reliability, speed and selectivity. They have constituted the most attractive alternatives for classical analytical methods in various fields such as food processing, medicine and clinical biology, or environmental quality control. In this work we are interested in the design and production of a multi-parameter electrochemical amperometric biosensor. This device makes it possible to measure the variation of the current following a chemical reaction. The induction of a redox reaction and the displacement of electrons generates an electric current which corresponds to a concentration.
