“…[5,[10][11][12][13][14] Moreover, many organic UV filters are also well-known for their photo-instability resulting in the production of carcinogenic reactive oxygen species (ROS) upon solar irradiation. [15][16][17][18] One prospective method to improve the stability of organic UV filters whilst also minimizing skin contact is to incorporate them into nanoparticles.…”

“…1 O 2 , the lowest excited state of molecular oxygen, can be used as a highly active oxidant in chemical, biological and environmental systems . 1 O 2 can be easily generated in solution by energy transfer from excited photosensitizers or chemically, which are the most common procedures . 1 O 2 has a standard potential E°( 1 O 2 / O 2 • ) equal to 0.65 V vs. NHE at pH 7 and its lifetime in aqueous solution depends on the presence of scavengers (DOM in natural waters), being 4 µs in pure water .…”

The direct measurement of the luminescence emitted by 1 O 2 has been carried out at 1270 nm, althought sometimes the weak signal recorded hinders the application of this direct analytical method .…”

“…Therefore, the following text will focus on frequently used detection techniques for this type of ROS. Wu et al have recently summarized methods of 1 O 2 detection [16], with focus on the recent technical advances. To investigate the chemistry of 1 O 2 , several analytical tools are available to obtain information about the concentration, the spatial distribution, and the temporal behavior of 1 O 2 formation, including spectrophotometry, fluorimetry, and (chemi)luminometry.…”
