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.

Oxidation of Catalase by Singlet Oxygen [PDF]
Journal of Biological Chemistry, 1998 Different bands of catalase activity in zymograms (Cat-1a-Cat-1e) appear during Neurospora crassa development and under stress conditions. Here we demonstrate that singlet oxygen modifies Cat-1a, giving rise to a sequential shift in electrophoretic mobility, similar to the one observed in vivo. Purified Cat-1a was modified with singlet oxygen generated

Properties and usage of water after quenching of singlet oxygen
, 2022 S.310-312Water is a well-known quencher for singlet molecular oxygen. The dissipation of the energy from singlet molecular oxygen was found to cause physical changes of the water that could be detected by infraredspectroscopic investigation of the water ...
