Redox proteins for the development of biosensors

Abstract

In recent years the field of chemical sensors and optical biosensors has been developed considereably. A biosensor is a device composed of a biological component (Borisov and Wolfbeis 2008) that interacts with a target analyte (ion, molecule, etc.), in a highly specific and selective translation of a chemical or biological response into a measurable physical signal. A biosensor offers several advantages. In fact, it is highly specific with reproducibility in measurements, and a rapid response. The decisive impetus to this development was initially received by the medical industry. However, other sectors such as food quality control as well as environmental monitoring have expressed a recent growing interest in this area. There is therefore a need for a multidisciplinary approach to the subject. [edited by Author]
