ENZYMATIC GROOMING OF ORGANIC THIN-FILMS

As if with a razor, single polypeptide chains that extend significantly above the bulk layer of polypeptides can be shaved off with ala‐nine and leucine aminopeptidases. In the preparation of tightly packed layers of helical peptides, the lengths of the peptide chains cannot be controlled; with the enzymatic grooming process described here subsequent smoothing is possible, which is important for potential applications of these layers as waveguide materials.
