[Biological structures as photonic objects].

Samples of the material of mollusks bowls, peacock wing elements, and human horn skin have been investigated using the methods of spectroscopy, atomic-force microscopy, X-ray diffraction analysis, and thermoconductance. Ordered superstructures were revealed in these objects. Evidence for effective interactions of both electromagnetic and electronic waves with these structures was obtained. It was shown that the interaction with electromagnetic waves reveals photonic properties and the interaction with electronic waves, the semiconducting properties of biological objects.
