Outline of Final Research Achievements

Although the rare metals are used in various instruments, they will be depleted in the near future. Thus we have to recycle them from the urban mines. Here we present peptides that have capability of selectively binding and recycling the rare metals. One of the designed peptides is specific to gold, another is to platinum, and the other binds to various rare metals or rare earths such as Pd, Cs, Dy, and Nd. Furthermore the gold binding peptide was found to gradually interconvert the gold ion into the nano colloid concomitant with a change in color to magenta. This study will serve as a stepping stone to further development to recycling and sensing rare metals.
