The structure of LB films of protein-polyelectrolyte complexes transferred onto the pyrographite surface was studied by STM. The images of the films obtained at various protein concentrations in the water subphase and different values of surface pressure were captured. The topology of the surface covered by one or three layers of the films studied was investigated. It is shown that at a protein concentration of 1 mg/ml in the water subphase, the films are composed of aggregated protein molecules, and their structure has an insular character. An increase in the number of transferred layers up to three results in a virtually complete covering of the surface. A decrease in the protein concentration in the water subphase to 1 microgram/ml enabled us to prepare films consisting of individual non-aggregated protein molecules. |
