Genetically modified organisms (GMOs) are plants or animals whose genetic make-up has been transformed by recombinant DNA technology, which has new features such as resistance to herbicides, virus and insect. Recently, genetic modification of food products has increased in order to reduce world poverty and hunger and increase food production However, the impact of GMOs on the human health is a growing concern worldwide. Due to increased global production of GMOs, the presence of these in food products need to be monitored and has been attended by many researchers recently. The quick, simple, accurate and sensitive detection methods for these products have attracted the attention. Electrochemical DNA biosensors as one of these fast methods are highly studied by many researchers due to their high sensitivity, low cost, rapid reaction and the possibility of working in aqueous solutions. The present review will focus on several studies on the detection of GMO based on electrochemical biosensors.
