Plant Sensors Made from Carbon Nanotubes Can Serve as Early Warning System for Farmers

Researchers from MIT and SMART have developed plant sensors using carbon nanotubes to detect stress signals in plants, providing early warnings for farmers. By monitoring hydrogen peroxide and salicylic acid levels, the sensors can alert farmers to potential threats and allow for proactive measures. The sensors can be customized to detect different molecules and are applied to plant leaves to provide real-time information on plant stress responses.
