Electrochemical Detection of Phytohormones in Agricultural Systems
Summary
Phytohormones are endogenous signalling molecules that regulate plant growth, development and stress responses. Monitoring their concentrations in soils, hydroponic solutions or plant tissues is crucial for optimising crop yield, diagnosing stress and guiding precision agriculture. Electrochemical detection offers rapid, sensitive and low‐cost analysis through direct redox measurements of target hormones. Advances in electrode modification—incorporating nanostructured films, carbon‐based materials and biorecognition elements—have improved selectivity, lowered limits of detection and enabled real‐time assessment in complex matrices. Integration with portable potentiostats and wireless data transmission paves the way for in‐field sensors capable of continuous monitoring, supporting resource‐efficient management and early stress intervention in diverse agricultural settings.
