Chemical sensors and biosensors for the control of GM food
Languages of publication
European Community regulations concerning the control of use and distribution of genetically modified organisms and products resulted in creation of European and National GMO Laboratories Networks, which are specialized in GMO identification and quantification in food, feed and seed. The analyses are mainly based on PCR methods, however, cheaper and less time consuming methods are elaborated for GMO detection. This article summarizes the research on electrochemical biosensors based on nucleic acids hybridization and the perspectives these tools create.
