Total reflection X-ray fluorescence study of organic nanostructures

X-ray scattering techniques based on total external fluorescence study and development of X-ray standing wave method are presented and used for characterization of organic nanostructure Langmuir-Blodgett films of fatty acid salts and phospholipids. Spectral selectivity of data obtained allows us to detect structure position of different ions in organic systems, to obtain information about interdiffusion at the interfaces, about ion permeation through organic bilayers, thus allowing us to develop models of biomembranes.
