Nanosensors for food safety.

This review summarizes recent research and development of nanosensors applied to the food safety. Since the food safety is directly related to the people's health and life, the food detection has received considerable attentions. However, this food security has emerged in China as a severe problem in recent years. Food safety problems frequently compromised due to formaldehyde, poison vegetables, excessive pesticide residues, etc. These kinds of food contaminations could not be detected efficiently by traditional methods. Applying nanotechnology and nanominerals, various food contaminations can be identified accurately. Therefore nanosensors have been widely used in the food detection. We introduce current research on nanosensors followed by the industrial application of nanosensors. Finally, the challenges for the future food safety using nanosensors are discussed.
