A method, apparatus, and computer usable program code for non-destructive detection of corrosion using quantum dots. In one embodiment, a surface of an area on a commodity associated with a set of quantum dots is tested. A pattern of wavelengths emitted by the set of quantum dots associated with the surface of the commodity is detected to form a quantum dot pattern. The quantum dot pattern is analyzed to determine whether corrosion has occurred in the area on the surface of the commodity.
