methods of deposition of thin organic (and bioorganic) films by
the successive transfer of monolayers of surfactant compounds
from the air-water interface onto the solid substrate.
materials used includes ordinary amphiphilic molecules of
various classes, polymers, lipids, phthalocyanines, porphyrins,
charge-transfer complexes and salts, polypeptides, enzymes,
antibodies, and other proteins, nucleic acids.
