Scientists at MIT have incorporated sensors in "carbon nanotubes" and placed them in spinach leaves enabling the plant to detect a wide range of molecules. These "nanobionic spinach" have detected explosives in subterranean waters, "hydrogen peroxide", sarin gas and even "trinitrotoluene" - a type of explosive.
Spinach fitted with sensors  could therefore be used to reveal numerous pollutants and trace elements. The plants could also be used to locate dryness and several changes in soil properties.
This is a first step towards digitising plant information. The ultimate aim is to improve our knowledge of environmental sciences, agriculture and health.
 The spinach is not edible!
