Freeze frame: Scientists capture atomic-scale snapshots of artificial proteins
(PHYSorg.com Nanotechnology)

Protein-like molecules called `polypeptoids` (or `peptoids,` for short) have great promise as precision building blocks for creating a variety of designer nanomaterials, like flexible nanosheets-ultrathin, atomic-scale 2-D materials. They could advance a number of applications-such as synthetic, disease-specific antibodies and self-repairing membranes or tissue-at a low cost.
