[Photochemical stability of aromatic amino acids under picosecond laser UV-irradiation].
Two-step photochemical decomposition of aromatic amino acids under picosecond laser UV-irradiation was investigated. These results were compared with the photochemical stability of nucleic acid bases. Using the known ratio between the nucleic acid bases and aromatic amino acids in native bacteriophages lambda and phi X174 it was shown that picosecond laser UV-inactivation of viruses occurred due to the photodegradation of nucleic acid.
