WS2 (P53): Development of Glutamate-EnFET-based enzymatic microsensors for food analysis

International audience; Glutamic acid and especially its associated glutamate ion are additives widely used as food 147lavor. enhancers as well as main markers of the Japanese taste umami. As a result, monosodium glutam (MSG). is widely used as an additive by the food industry. However, excess consumption may be responsible for. brain disorders causing sweats, headaches, losses of balance, faints and pains, schizophrenia, Alzheimer’s. and Parkinson’s disease[1] . Thus, it became important to develop methods in order to analyze glutamate. ions in liquid phase and to integrate them in order to realize glutamate-sensitive microsensors. This paper presents the development of ElecFET (Electroche…
