Breakthrough Nanosensor Monitors Iron in Living Plants
2025-03-11
Researchers at the Singapore-MIT Alliance for Research and Technology (SMART) have developed a groundbreaking near-infrared (NIR) fluorescent nanosensor capable of simultaneously detecting and differentiating between Fe(II) and Fe(III) in living plants. This real-time, non-destructive sensor enables precise monitoring of iron uptake, transport, and transformations, offering insights into plant nutrition and informing precise fertilization strategies. The technology, applicable to various plant species, promises advancements in agriculture and beyond, with potential applications in environmental monitoring and health sciences.
