Porphyrin-Containing MOFs and COFs as Heterogeneous Photosensitizers for Singlet Oxygen-Based Antimicrobial Nanodevices.

ACS Applied Materials and Interfaces, 2021
Visible-light irradiation of porphyrin and metalloporphyrin dyes in the presence of molecular oxygen can result in the photocatalytic generation of singlet oxygen (1O2).

Almost 100% peroxymonosulfate conversion to singlet oxygen on single-atom CoN2+2 sites.

Angewandte Chemie, 2020
Single-atom CoN 4 active sites have demonstrated excellent efficiency in peroxymonosulfate activation. However, the identification of CoN 4 active sites and the detailed singlet oxygen generation mechanism in peroxymonosulfate activation still remain ...

Singlet Oxygen in Photosensitization

Journal of Environmental Pathology, Toxicology and Oncology, 2006
Oxygen is a ubiquitous element and a vitally important substance for life on the Earth, and especially for human life. Living organisms need oxygen for most, if not all, of their cellular functions. On the other hand, oxygen can produce metabolites that are toxic and potentially lethal to the same cells.

Review of Chemical Reactivity of Singlet Oxygen with Organic Fuels and Contaminants

The chemical record, 2020
Singlet oxygen represents a form of reactive oxygen species (ROS), produced by electronic excitation of molecular triplet oxygen. In general, highly reactive oxygen‐bearing molecules remain the backbone of diverse ground‐breaking technologies, driving ...

Proline is a quencher of singlet oxygen and superoxide both in in vitro systems and isolated thylakoids.

Physiologia Plantarum : An International Journal for Plant Biology, 2020
Proline is a versatile plant metabolite, which is produced in large amounts in plants exposed to osmotic and oxidative stress. Proline has been shown to provide protection against various reactive oxygen species (ROS), such as hydrogen peroxide and ...

Specific Generation of Singlet Oxygen through the Russell Mechanism in Hypoxic Tumors and GSH Depletion by Cu-TCPP Nanosheets for Cancer Therapy.

Angewandte Chemie, 2019
The generation of singlet oxygen (1 O2 ) during photodynamic therapy is limited by the precise cooperation of light, photosensitizer, and oxygen, and the therapeutic efficiency is restricted by the elevated glutathione (GSH) levels in cancer cells ...

Oxygen vacancy enhanced singlet oxygen production for selective photocatalytic oxidation.

ChemSusChem, 2020
Oxygen vacancy is usually thought to be beneficial for photogenerated charge separation. In this work, the oxygen vacancy in ov-Bi 2 O 3 (Bi 2 O 3 with oxygen vacancy) is found to be able to produce 1 O 2 in the dark due to chemical adsorption.
