Active search for new materials with controllable optical properties has resulted in the invention of new class of optical materials called photonic crystals. These materials consist of periodically arranged dielectric globules or cavities with sizes comparable to the wavelength of light [1]. An infiltration of biological molecules in PC leads to a change of dielectric property of environmental medium between the structural elements of PC and the change in stop zone formation. On the other hand, the optical property of biological molecules, introduced in the confined volume of the photonic crystal air holes, could be changed also. DNA, being a unique molecule, has a size that is close to the spacing between structural elements in synthetic opal. That is why the goal of our study is to register Raman scattering (RS) modes of separated DNA molecules in confined volume. In our experiments we used the DNA water solution (1 mg/ml). RS spectra have been registered with Renishaw in Via Raman microscopy instrument in the 200-2000 cm-1. Nanodisperse silica globules were synthesized by the Stöber method[2]. Growth of the photonic crystals was achieved by subsequent natural sedimentation. The RS marker bands of DNA were drastically changed after its infiltration in the porous of opal. A structure of the DNA molecule in confined volume could be used as a model of DNA folding in the living cell.
