Singlet oxygen imaging using fluorescent probe Singlet Oxygen Sensor Green in photosynthetic organisms

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.

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...

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 Trapping Porphyrins

Fiber-optic Singlet Oxygen

Traditionally, Type II heterogeneous photo-oxidations produce singlet oxygen via external irradiation of a sensitizer and external supply of ground-state oxygen. A potential improvement is reported here. A hollow-core fiber-optic device was developed with an ‘‘internal’’ supply of light and flowing oxygen, and a porous photosensitizer-end capped configuration. Singlet oxygen was delivered throu...
