the usage nanosensors in packaging and preservation of food

nanotechnology in manufacturing of sensors with small dimensions, evaluate a lot of the parameters carefully. the applications of nanosensors include three important branch in nan biotechnology (medical, agricultural and food industries). nan osensors technology as a new science is a powerful substitution for conventional analytical techniques in the field of agricultural sciences. sensitivity and selection of nanosensors provide the possible development of special devices for analysis of complex mixtures without the need for immediate preparation of examples. research and development of these nanosensors are in the field of health, environmental application, and food industy. nano-sensor packaging is another types of nanotechnology application in food industrial packaging. these packaging can be evaluated temperature and humidity at different time and give appropriate response to consumer depending on the circumstances. for example, for changing the moisture content the color of container changes. this material may give warning to consumers that the food or agricultural product is corrupt. application nanosensors is important in the food industry, in this article nanosensors applications in food packaging (detection of food pathogens and chemical contaminants and identify chemical toxic in food) have been discussed.
