These spinach plants can send out e-mails, and it can save the environment Using nanotechnology, these spinach plants are able to relay this information to the scientists in the form of an e-mail BusinessToday.In | February 2, 2021 | Updated 19:55 IST Spinach roots can detect the presence of a specific explosive material in the groundwater Plants sending out e-mails sounds like a concept from a science-fiction film set in the distant future. This feat has actually been achieved in 2021 as scientists in the real world have managed to engineer spinach plants that are capable of sending out emails. Engineers at Massachusetts Institute of Technology (MIT) through the use of nanotechnology have transformed spinach plants into sensors which have explosive material detection capabilities. Using nanotechnology, these spinach plants are able to relay this information to the scientists in the form of an e-mail.
