Endogenous Singlet Oxygen Photosensitizers in Plants. [PDF]

, 2016
Singlet oxygen, a highly reactive oxygen species, is inherently produced in chloroplasts of plants. Chlorophylls are used by plants to harvest light and to transport the singlet electronic excitation from the antenna complexes to the reaction centre (RC)

Dual‐Responsive Hydrogels Integrate Bioelectrical Stimulation and Piezo‐Photocatalysis for Regenerative Treatment of Infected Wounds

Advanced Science, EarlyView.
A wireless, dual‐responsive hydrogel (PVA/(PVDF‐TrFE)/BiOClBr@PDA) is developed to promote efficient regeneration of infected wounds by integrating piezoelectric stimulation with piezo‐photocatalytic pathways. Under simultaneous light and ultrasonic stimulation, the hydrogel generates therapeutic electrical cues and reactive oxygen species, disrupting ...

Self‐Healing Pd(II) Cage Metallogels for Iodine Capture in Water and Heterogeneous Photocatalysis

Advanced Science, EarlyView.
Two carbazole‐derived metal‐organic cages hierarchically self‐assemble into supramolecular metallogels that integrate autonomous self‐healing, reversible stimuli responsiveness, high‐capacity aqueous iodine capture, and visible‐light‐driven photocatalytic sulfide oxidation within a single multifunctional platform.

Near‐Unity Photothermal Conversion in Bimetallic M44 and M81 Nanoclusters Enables NIR‐Driven Photo‐Thermo‐Electricity Generation

Advanced Science, EarlyView.
Atomically precise nanoclusters of Au/Ag alloys are explored as high‐performance photothermal materials, delivering record‐high photothermal efficiencies (up to 91%). Photo‐thermo‐electricity is further demonstrated by integrating nanocluster films with thermoelectric devices.

Singlet Oxygen Generation in Classical Fenton Chemistry [PDF]

, 2019
The Fenton reaction, the Fe-catalyzed conversion of hydrogen peroxide to reactive oxygen species (ROS) was discovered more than a century ago. It occurs widely in nature because of the ubiquity of Fenton reagents, i.e., Fe and H2O2, and ROS in ...

Significance of Singlet Oxygen Molecule in Pathologies

, 2023
Reactive oxygen species, including singlet oxygen, play an important role in the onset and progression of disease, as well as in aging. Singlet oxygen can be formed non-enzymatically by chemical, photochemical, and electron transfer reactions, or as a ...

Imaging the production of singlet oxygen in vivo using a new fluorescent sensor, Singlet Oxygen Sensor

, 2006
Singlet oxygen is known to be produced by cells in response to photo-oxidative stresses and wounding. Due to singlet oxygen being highly reactive, it is thought to have a very short half-life in biological systems and, consequently, it is difficult to ...

Independent Control of Singlet Oxygen and Radical Generation via Irradiation of a Two-Color Photosensitive Molecule

, 2019
Free-radical polymerizations are used for a wide range of applications but are detrimentally impacted by the presence of oxygen. Zinc phthalocyanines have been previously used as singlet oxygen generators to excite radical-consuming ground-state triplet ...
