The surface morphology and optical activity of films based on chitosan in different chemical forms were investigated by methods of scanning electron and atomic force microscopy, spectropolarimetry. These film samples are used as substrates for optical waveguides, sorption material and as substrates for cell culturing tissue-engineering and scaffold constructions. The essential differences in the structural and morphological relief of thin films from chitosan of different chemical forms are established. It was found that the spectra of optical rotatory dispersion and circular dichroism of films of chitosan in the form of polysalts and polybases are significantly different in absolute values of the optical rotation of the plane and circularly polarized light.
