Singlet Oxygen in Photodynamic Therapy
PharmaceuticalsPhotodynamic therapy (PDT) is a therapeutic modality that depends on the interaction of light, photosensitizers, and oxygen. The photon absorption and energy transfer process can lead to the Type II photochemical reaction of the photosensitizer and the ...

Singlet Sigma: The “Other” Singlet Oxygen in Solution [PDF]
Photochemistry and Photobiology, 1999 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]
EPJ Web of Conferences, 2019 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

Singlet oxygen luminescence detector based on low-cost InGaAs avalanche photodiode
HardwareX, 2021 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,

Erythrocuprein and singlet oxygen
FEBS Letters, 1972 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].

Generation of singlet oxygen via iron-dependent lipid peroxidation and its role in Ferroptosis
Fundamental Research, 2022 Ferroptosis is a cell death pathway mediated by iron-dependent accumulation of lipid peroxide. However, the specific downstream molecular events of iron-dependent lipid peroxidation are yet to be elucidated.
