A Comprehensive Tutorial on In Vitro Characterization of New Photosensitizers for Photodynamic Antitumor Therapy and Photodynamic Inactivation of Microorganisms
Figure 2
Formation of the endoperoxide of SOSG (singlet oxygen sensor green) upon reaction of SOSG with 1O2 as an indirect method for detecting 1O2. Prior to the reaction with 1O2, internal electron transfer (ET) quenches the fluorescence from the light-emitting chromophore. Upon reaction with 1O2 and the formation of the endoperoxide, electron transfer is precluded, and fluorescence is observed.
