The surface pressure-area isotherms of bilirubin (BR) monolayers at an air-water interface on subphases with and without metal ions were investigated. The formation of BR-metal complexes leads to changes in the shape of isotherms of BR and changes in UV-visible absorption spectra of the monolayer assemblies. In XPS spectra new XPS peaks assigned to the metal ions containing subphases appeared. Low-angle X-ray diffraction indicates this Y-type LB films of MBR were formed with bilayer spacing of ca. 2.1 nm.
