Conclusion
UV induced ds(ss)-DNA damage in buffer solution and in wet, dry absorbed layer, using optical and photoluminescence spectroscopy, as well as conductivity was revealed. Models of UV induced ds(ss)-DNA damage were accounted in the photochemical reactions of cyclobutane-pyrimidine dimmer and (4–6) adduct formation were used to recognise ds(ss)-DNA damage in their absorption spectra and wet ds-DNA damage in photoluminescence spectra and in the behaviour of conductivity under periodical switched of UV irradiation.
But it's important to develop offered methods for its further ability to direct evident possible photochemical reaction that took place in ds (ss)-DNA.
