The University of Guelph is developing a device for people with serious food allergies. It detects allergens in the food, determining in just minutes whether the food is safe to eat. The device is wallet-sized and contains micro-fluidics and nano-equipment, so only a small food sample is required. It so far can test for peanuts and gluten, and researchers are working to expand its capabilities to track other allergens, such as shellfish. It also can connect to a mobile app, making it more user friendly.
Would you use a tool like this? Do you trust your friends and family when they say the food is free of allergens?
