Singlet Oxygen Delivery Through the Porous Cap of a Hollow-Core Fiber Optic Device [PDF]

open access: yes, 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,

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 ...

Direct measurement of singlet oxygen produced by four chlorin-ringed chlorophyll species in acetone solution [PDF]

open access: yes, 2010
We developed an optical system to detect singlet oxygen produced by chlorin-ringed chlorophyll (Chl) species, i.e., Chl a, Chl b, Chl d, and di-vinyl-Chl a, with a high sensitivity and examined the relationship between molecular structures and reaction ...

Generation of superoxide and singlet oxygen from α-tocopherolquinone and analogues. [PDF]

open access: yes, 2007
Three potential routes to generation of reactive oxygen species from a tocopherolquinone have been identified. The quinone of the water-soluble vitamin E analogue Trolox C (Trol-Q) is reduced by hydrated electron and isopropanol a hydroxyalkyl radical ...

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

Studies on Production and Chemical Property of Singlet Oxygen and Superoxide Radical by Dyestuffs

open access: yesE-Journal of Chemistry, 2009
There are several low lying singlet oxygen (1O2) and superoxide radical (O-2) which are important in photochemical oxidation. In our present analysis we are studying chemical property of singlet oxygen (1O2) and super oxide radical (O-2) and some ...
