Generation of singlet oxygen via iron-dependent lipid peroxidation and its role in Ferroptosis

open access: yesFundamental 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 in Antimicrobial Photodynamic Therapy: Photosensitizer-Dependent Production and Decay in E. coli

open access: yesMolecules, 2013
Several families of photosensitizers are currently being scrutinized for antimicrobial photodynamic therapy applications. Differences in physical and photochemical properties can lead to different localization patterns as well as differences in singlet ...

Oxidation of Catalase by Singlet Oxygen [PDF]

open access: yesJournal 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

Study of Singlet Oxygen Dynamics on Silicon Polymer Matrix

open access: yesJournal of Analytical Methods in Chemistry, 2019
We report a detailed analysis of singlet oxygen generated from the photofunctional polymer film (PFPF) matrix which is the silicone polymer film (PDMS) embedded with a photosensitizer. Activation and deactivation dynamics of singlet oxygen generated from

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Characterization of singlet oxygen-accumulating mutants isolated in a screen for altered oxidative stress response in Chlamydomonas reinhardtii

open access: yesBMC Plant Biology, 2010
Background When photosynthetic organisms are exposed to harsh environmental conditions such as high light intensities or cold stress, the production of reactive oxygen species like singlet oxygen is stimulated in the chloroplast.
