Hydrogel Microneedle-Enabled In Situ Monitoring of Leaf Nitric Oxide for Evaluating NO Nanoprodrug-Mediated Salt Stress Alleviation in Maize.
Chemical signals in living plants are spatially confined, rapidly consumed, and strongly dependent on the delivery history of exogenous regulators, creating a need for bioelectronic interfaces that can interrogate molecular dynamics directly within intact tissues. Here, we integrate a nitric oxide (NO) nanoprodrug with...
