Polymeric peptide pigments with sequence-encoded properties
Abstract
Melanins are a group of natural pigments that are the primary factor affecting skin color. Lampel et al. examined a family of melanin-inspired materials based on tripeptides containing tyrosine as precursors for polymeric pigments. They found that the supramolecular organization of the tripeptide assembly is the most important factor for the enzymatic oxidation, with the position of the tyrosine residue playing a dominant role. Thus, simply juggling the order of the peptides allowed tuning of the optical and electrical properties of the resulting polymers.
