Cytotoxicity Induced by Tetracyclines via Protein Photooxidation

Figure 8

Photodegradation of all tetracyclines dissolved in a mixture of phosphate buffer and DMSO (50 : 50). The graph shows the kinetics of first-order in which the molecules are photodegraded ( value of absorbance after the solution has absorbed 15 J/cm2 of irradiation in 30 minutes value of absorbance at 0 J/cm2).
