Modulation of 5-Aminolevulinic acid mediated photodynamic therapy induced cell death in a human lung adenocarcinoma cell line [PDF]
, 2016 Photodynamic therapy (PDT) is a cancer treatment involving the administration of a photosensitising drug which selectively accumulates in tumor tissue, followed by irradiation with appropriate wavelength light.

Advanced Functional Materials, EarlyView.A facile and effective method to boost NIR light induced photocatalysis based on nontoxic NIR emissive carbon dots (nir‐CDs) via Self‐trapped excitons, showing that both O2− • and •OH can be generated from nir‐CDs under NIR laser irradiation. Abstract Near‐infrared (NIR) light‐triggered photocatalytic therapy remains a critical challenge in efficient ...

Near-Infrared Phosphorescence of Raman Photogenerated Singlet Oxygen
PhotochemWe report on the phosphorescence of singlet oxygen photogenerated through a stimulated Raman process. Nanosecond radiation in the green spectral region focused on hexane and carbon tetrachloride induces a Raman transition of the dissolved solvent oxygen ...

Fingerprints for spin-selection rules in the interaction dynamics of O2 at Al(111)
, 2008 We performed mixed quantum-classical molecular dynamics simulations based on first-principles potential-energy surfaces to demonstrate that the scattering of a beam of singlet O2 molecules at Al(111) will enable an unambiguous assessment of the role of ...

Advanced Functional Materials, EarlyView.Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...

Singlet oxygen-mediated selective C–H bond hydroperoxidation of ethereal hydrocarbons
Nature Communications, 2017 Singlet oxygen is known to react with carbon–carbon double bonds. Here, the authors show the unusual functionalization of α-ethereal C–H bonds mediated by singlet oxygen under mild conditions to afford lactones and hydroperoxide products.

Singlet oxygen production in photosynthesis [PDF]
Journal of Experimental Botany, 2004 A photosynthetic organism is subjected to photo-oxidative stress when more light energy is absorbed than is used in photosynthesis. In the light, highly reactive singlet oxygen can be produced via triplet chlorophyll formation in the reaction centre of photosystem II and in the antenna system. In the antenna, triplet chlorophyll is produced directly by

Infrared laser pulse triggers increased singlet oxygen production in tumour cells [PDF]
, 2013 Photodynamic therapy (PDT) is a technique developed to treat the ever-increasing global incidence of cancer. This technique utilises singlet oxygen (1O2) generation via a laser excited photosensitiser (PS) to kill cancer cells.
