Spinach is well known as an excellent source of Vitamin K, Vitamin A, manganese, folate, magnesium, iron, copper, vitamin B2, vitamin B6, vitamin E, calcium, potassium and vitamin C. It is a very good source of dietary fiber, phosphorus, vitamin B1, zinc, protein and choline.
But did you know that spinach plants can also detect explosives?
Engineers at MIT have embedded the spinach leaves with carbon nanotubes and have transformed the spinach plants into sensors that can detect explosives and wirelessly transmit that information to a small computer similar to a smartphone. Plants were designed to detect chemical compounds known as nitroaromatics, which are often used in landmines and other explosives. When one of these chemicals is present in the groundwater sampled naturally by the plant, carbon nanotubes embedded in the plant leaves emit a fluorescent signal that can be read with an infrared camera. The camera can be attached to a small computer similar to a smartphone, which then sends an email to the user.
This discovery has overpower the plant/human communication barrier.
