Several illnesses are caused by the distribution of food. The usual methods of testing for the likes of Salmonella and E-Coli take days and are pretty expensive. A marine biologist is using nanotechnology to create a sensor that can detect food pathogens in a matter of hours. E-nose could prevent outbreaks stemming from a number of places including restaurants and factories. It is still being tested but recent results have shown the sensor is 94% accurate and takes only six hours to deliver results. If approved, food companies could be offered a subscription package to save costs.
