Abstract

Calf skin collagen molecules adsorbed on a graphite substrate were directly imaged by scanning tunneling microscopy in air. The right-handed helical structures were observed and the average periodicity was quantitatively measured to be 31 Å, in good agreement with the value of about 28 Å estimated from biochemical studies. The intermolecular distance in a collagen bundle was 23 Å.
