Optical properties of photonic crystals (synthetic opals) with DNA inserted inside the crystals have been registered and analyzed in the visible and IR ranges. A decrease in the intensity of vibration spectra of DNA infiltrated in opal is observed. Molecules of DNA placed in the cavities of a photonic crystal became invisible for the detection by visible and IR spectroscopies. Spectroscopic features of DNA in a photonic crystal indicate the formation of condensed DNA inside and at the surface of the photonic crystal. The emission of the 'DNA - photonic crystal' system has been registered at room temperature. By confocal microscopy, we have visualized DNA at the surface of a photonic crystal. The experimental results are explained by assuming the formation of coupled photonic states of DNA and a photonic crystal. [ABSTRACT FROM AUTHOR] |
