Fertilizer nano-particles comprising a coating (e.g, a cellulose derivative) and a DNA aptamer, which binds to compounds released by the roots during active nutrient uptake.
About
Coated particles for delivering agrochemical to the roots of a plant comprising a cellulose derivative, a fatty acid, and an aptamer that binds specifically to an exudate released by the roots of the plant when the plant is actively taking up nutrients from the soil. The permeability of the coating increases when the DNA aptamer within coated particles binds to the exudate synchronizing nutrient release with uptake of the nutrients during active growth.
