Phosphoprotein SAK1 is a regulator of acclimation to singlet oxygen in Chlamydomonas reinhardtii
Singlet oxygen is a highly toxic and inevitable byproduct of oxygenic photosynthesis. The unicellular green alga Chlamydomonas reinhardtii is capable of acclimating specifically to singlet oxygen stress, but the retrograde signaling pathway from the ...

Singlet oxygen luminescence detector based on low-cost InGaAs avalanche photodiode
Molecular oxygen excited to singlet state (Singlet oxygen, 1O2) becomes highly reactive and cytotoxic chemical. 1O2 is commonly generated by photoexcitation of dyes (photosensitizers), including the photodynamic therapy and diagnostics of cancer. However,

Singlet Sigma: The “Other” Singlet Oxygen in Solution [PDF]
AbstractThe lowest excited electronic state of molecular oxygen, O2(a1‐DLg), is often called simply singlet oxygen. This singlet delta state is an acknowledged and well‐studied intermediate in many solution‐phase photosystems. However, the second excited electronic state of oxygen, O2(b1δg+), is also a singlet.

Temperature dependence of singlet oxygen generation by different photosensitizers [PDF]
The temperature dependences of the lifetimes and the efficiency of singlet oxygen generation for a set of compounds (porphyrins, metalloporphyrins, porphycene, terrylene etc.) has been measured and characterized. Based on the character of the temperature

Erythrocuprein and singlet oxygen
McCord and Fridovich [ 1,2] have shown that erythrocuprein, the copper and zinc containing protein extracted from red blood cells, can enzymatically disproportionate superoxide radicals (Oh), an intermediate of the reduction of oxygen, the generation of which in some Ha 0s -producing biological oxidations has been demonstrated [3].
