New Sensor Could Help Prevent Food Waste
To test the new sensor's capabilities, the researchers deposited the carbon nanotubes and other sensor components onto a glass slide. They then used it to monitor ethylene production in two types of flowers โ€” red carnations and purple lisianthus.

Monitoring the plant hormone ethylene could reveal when fruits and vegetables are about to spoil.
