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.

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.

Singlet Oxygen Delivery Through the Porous Cap of a Hollow-Core Fiber Optic Device [PDF]
, 2009 The development of the first photosensitizer/fiber optic device is reported. An oxygen-flowing, fiber-capped configuration is used for the application of heterogeneous, spatially confined singlet oxygen delivery in aqueous media. This is a unique device,
