An iron/shikonin nano-composite and a use thereof, and a method for preparing the same by supermolecular self-assembly, belonging to the technical field of functional materials. The composite consists of shikonin and ferric ions, wherein shikonin is coordinated with the ferric ions, and the hydroxyl and carbonyl groups in shikonin are coordinated with the ferric irons to form a complex, which is then assembled by π-π stacking and hydrophobic interactions to form a nano-composite which exhibits glutathione response. The composite is obtained by the following steps: adding an aqueous solution of a ferric salt and an organic solvent solution of shikonin in sequence into water while stirring at ambient temperature, continuously stirring at ambient temperature, and centrifuging the resulting mixture to purify, thereby obtaining an iron/shikonin nano-composite in the resulting solution.
