Selective uptake and sensing of nitrate in poly(3,4-ethylenedioxythiophene)

Nitrogen (N) as a nutrient, in the form of nitrate (NO(3) (−)), is essential for plant growth. Chemical fertilizers are used to increase crop yields, but overuse can lead to forms of environmental pollution necessitating methods to detect and monitor the level of NO(3) (−) in-situ in agricultural so...

description Nitrogen (N) as a nutrient, in the form of nitrate (NO(3) (−)), is essential for plant growth. Chemical fertilizers are used to increase crop yields, but overuse can lead to forms of environmental pollution necessitating methods to detect and monitor the level of NO(3) (−) in-situ in agricultural soils. Herein we report for the first time the NO(3) (−) selectivity of the inherently conducting polymer poly (3,4-ethylenedioxythiophene) (PEDOT). This selectivity occurs when PEDOT thin films are exposed to an aqueous environment containing not only NO(3) (−), but a mixture of other ions present in concentrations (ppm) typical of real agricultural soil. The PEDOT sensitivity to absorb NO(3) (−) from solution is determined to be <1 ppm.
