Citrate-coated cobalt ferrite nanoparticles for the nano-enabled biofortification of wheat.

A pot experiment was conducted in an open greenhouse to explore the use of citrate-coated cobalt ferrite nanoparticles (CoFeO NPs) as a source for Fe fortification of three wheat lines ( L.). Two of the three wheat lines tested differ in their efficiency concerning Zn storage in their grains (efficient and inefficient), and one had inefficient P-absorption.
