Identification of Near-Uv Chromophores and Characterization of Cellular Responses to Near-Uv Damage and Oxygen Stress

The process in which a chromophore(s) absorbs light energy and transfers it to a cell in a toxic manner is known as the photodynamic effect. DNA is the primary chromophore in the UV-C region of electromagnetic spectrum (100-280nm; also known as Far UV or germicidal-UV), and its interaction with UV-C has been extensively studied. However, DNA has very little absorbance in the UV-A region (315-400nm). The identification of chromophores that do absorb in the UV-A and UV-B region (280-315nm) is particularly important due to the potential decrease in protection from the ozone layer.
