Imaging the production of singlet oxygen in vivo using a new fluorescent sensor, Singlet Oxygen Sensor Green(R)

Singlet oxygen photosensitisation by the fluorescent probe Singlet Oxygen Sensor Green.

The fluorescent probe Singlet Oxygen Sensor Green is able to produce singlet oxygen under exposure to UV or visible radiation.

A Singlet Molecular Oxygen Imaging Sensor for Photodynamic Therapy

Singlet oxygen is believed to be the species destroying cancerous cells during PDT. An optically-based imaging device for monitoring singlet oxygen production in a tumor was developed and tested in-vivo. ©2008 Optical Society of America OCIS codes: (170.0110) Imaging systems; (170.5180) Photodynamic therapy

Singlet oxygen production in photosynthesis.

A photosynthetic organism is subjected to photo-oxidative stress when more light energy is absorbed than is used in photosynthesis. In the light, highly reactive singlet oxygen can be produced via triplet chlorophyll formation in the reaction centre of photosystem II and in the antenna system. In the antenna, triplet chlorophyll is produced directly by excited singlet chlorophyll, while in the ...

Singlet Oxygen

Singlet oxygen (O2) is a higher energy state molecular oxygen species. It is one of the most active intermediates involved in chemical and biochemical reactions. To fully appreciate the reactivity of O2, it is necessary to understand its physical and chemical nature. This paper reviews the generation, quenching and detection of O2. Its properties, possible chemical reactions are presented as we...
