Polydiacetylene monolayers functionalized with amino acids
- Univ. of California, Berkeley, CA (United States) Lawrence Berkeley Lab., CA (United States)
Monomolecular polydiacetylene films have been constructed from a series of lipid monomers functionalized with amino acids. A wide range of surfaces including plastics, glass, and metals can be conveniently coated with peptides using these films. The techniques of X-ray photoelectron spectroscopy, fluorescence microscopy, and contact angle measurements were used to characterize the films. These studies indicate that the amino acid head groups are localized at the film-ambient interface and suggest that the films are structurally ordered both laterally and vertically. Thus, polydiacetylene films may provide promising model systems for investigating the fundamental properties of interfaces. 17 refs., 3 figs.
