As shown in Figure 7, upon film irradiation, a significant decrease in DMA concentration can be observed for the SSO-doped samples, which is associated with the photosensitized formation of [O.sub.2]([sup.1][[DELTA].sub.g]) and the subsequent reaction of DMA with [O.sub.2]([sup.1][[DELTA].sub.g]) to yield DMA-[O.sub.2].
Photosensitized oxidation of the compounds in aqueous phase was carried out as well as biological tests using the parasite Leishmania tarentolae.
Researchers at The Ohio State University evaluated the effect of riboflavin photosensitized oxidation on soybean oil in salad dressing using differential scanning calorimetry (DSC), headspace oxygen, solid phase microextraction.
7), we found that upon HPD-PDT a rise in the temperature from 30 to 44[degrees]C strongly (by ca 2.5-fold) enhanced the generation of [O.sub.2.sup.-*] in EAC cells, which correlated well with the increase in the rate of their photosensitized killing.

Methylene blue unwinds DNA helices and, when photosensitized with white light, forms singlet oxygen species; these changes lead to single-strand breaks in DNA and oxidative alterations to guanine residues.

Artists have created 20-foot-high flowers that are photosensitized to open with the daylight and follow the sun.
This emulsion, introduced in the late 1870s, made it possible to produce nonperishable photosensitized glass plates in factories, thus making photography less complicated, more convenient, and cheaper, thanks to large-scale production of one of its key components.
