Nanoscale Sensors Measure Elusive Water Levels in Leaves
Published:16 Jun.2021    Source:Cornell University

Water regulation in leaves is vital to a plant's health, affecting its growth and yield, disease susceptibility and drought resistance. A breakthrough technology developed by Cornell University researchers uses nanoscale sensors and fiber optics to measure water status just inside a leaf's surface, where water in plants is most actively managed.

 
The engineering feat provides a minimally invasive research tool that will greatly advance the understanding of basic plant biology, and opens the door for breeding more drought-resistant crops. The technology could eventually be adapted for use as an agronomic tool for measuring water status in crops in real time.
