Researchers at MIT and the Singapore-MIT Alliance for Research and Technology (SMART) have developed innovative sensors that can detect when plants are experiencing stress from environmental factors. These sensors are sensitive to hydrogen peroxide and salicylic acid, molecules that are key indicators of plant health.
The sensors, made from carbon nanotubes, are applied to plants in a solution that is absorbed through the leaves. They can emit a fluorescent signal that corresponds to specific stressors, allowing farmers to identify and address issues like heat, excessive light, or pest attacks much more quickly than traditional methods.
This rapid detection is crucial because it provides farmers with the opportunity to intervene before the stress causes significant damage to the plant. It represents a shift towards more proactive and preventive crop management, reducing losses and increasing efficiency.
