Peptides with inorganic recognition abilities are identified and used to engineer smart biomaterials composed of a magnetic nanoparticle core and a peptide coated shell. Smart biomaterials specific for molybdenum-disulfide (MoS2-MNP) and gold (AuBP-MNP) are synthesized individually and shown to recognize and recover the target material, effectively. While well-characterized gold binding peptides are exploited for this application, MoS2 binding peptides are selected with phage display technology. Recently selected peptides are found to retain their binding ability in a wide range of pH, which is promising for their potential utilization in various mining sides such as tailing ponds. Besides, the strong binding peptides didn’t exhibit binding affinity higher than 10% against other materials could be find in the ponds (Al2O3, Fe2O3, CaO, MgO, SiO2, Zn, Cu, S, Tungsten). Finally, recycle of the particles after the dissociation of the metal from smart biomaterial is studied.
