Summary

Peptides isolated from a phage library have been effective in promoting the precipitation of amorphous germanium oxide from a precursor solution. The morphologies of germania formed under the influence of these library-isolated peptides were shown to be distinct from the GeO2 formed under similar conditions with homo poly-amino acids. The appearance of germanium oxide hollow spheres or core/shell nanostructures created under the influence of peptide Ge8 is clearly linked to the unique amphiphilic character of the peptide. The appearance of these unique structures represents the first time such morphologies have been seen in germania or created utilizing only an unmodified peptide. The ease of creating these interesting inorganic materials makes mis system attractive for the possible fabrication of materials appropriate for catalysis, optical and controlled release applications.
