Diamine Oxidase-Based Biosensors: Construction and Working Principles

The analyses of biogenic amines in fresh and processed food is of great importance not only for the potential risk these compounds have on human health, but also because these amines can perform as chemical indicators of food quality and enable to assess the food processing conditions and/or microbial contamination. In real life we should often conduct analyses, where several compounds with similar properties are simultaneously present in solutions. A good option for a rapid on-line detection of biogenic amines is the application of biosensors, as these devices enable to obtain results in a few minutes without preliminary treatment of the material analyzed.
