Directionally aligned helical peptides on surfaces.

Describes the construction of directionally oriented peptide layers 1000 angstroms thick by polymerization on gold and indium-tin-oxide glass. Use of a functionalized surface on which the initiation sits for polymerization are spaced at a distances consistent with the helical diameter of the peptide; Retention of helicity of polyalanine layer after heating at 180 degrees for seven days.
