Characterization of the P-, PC-, and PCN-coated surfaces. (A) SEM images of the peptide network-like nanostructures on P- and PC-coated surfaces. The same structures appear on a PCN-coated surface as well as the appearance, on the same surface, of CuNPs embedded on the peptide nanostructures. (B) EDS analysis of P-, PC-, and PCN-coated surfaces.
