Singlet Oxygen Detection: A Review of Recent Advances

As part of the search for and development of an optimal solution related to singlet oxygen ( 1 O 2 ) detection, an analytical review of research in this direction was carried out. 1 O 2 is one of the key participants in many biological processes, so its detection and numerical estimation are the subject of a close study by many research groups. To date, several approaches to the optical detection of 1 O 2 have been proposed, in most cases based on the registration of 1 O 2 luminescence in the near-infrared range of the spectrum. The review also presents various fluorescence probes, chemical traps and several other tools that are also used for 1 O 2 detection.
