Sensitized photo-oxidation of gadusol species mediated by singlet oxygen
(Elsevier Science SA, 2020-12)
Gadusols are efficient nature UV sunscreens with antioxidant capacity. The kinetics of the quenching reactionsof singlet oxygen O2(1Δg) by gadusol species was evaluated in aqueous solution as well as in the presenceof ...
Photosensitized generation of singlet oxygen from rhenium(I) complexes: A review
(Elsevier Science SA, 2020-09)
I examine the photophysical properties for a number of thirty-eight Re(I) complexes in dilute solutions along with efficiencies of singlet oxygen production. Due to the structural differences around the Re(CO)3 core, the ...
Reaction of singlet molecular oxygen, O2(1 Δg), with the Cinchona tree alkaloids: Effect of absolute configuration on the total rate constant
(2005)
Detection of O2(1Δg) emission, λmax = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, kT, and the reactive reaction rate constant, kR, for the reaction ...
Superhydrophobic surfaces as a source of airborne singlet oxygen through free space for photodynamic therapy
(American Chemical Society, 2020-04)
A superhydrophobic (SH) sandwich system has been developed to enable "contact-free" airborne singlet oxygen (1O2) delivery to a water droplet. The contact-free feature means that the sensitizer is physically separated from ...
Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav.
(Taylor & Francis Ltd, 2009-12)
The singlet oxygen (1O2) quenching and free radical (DPPH+, ABTS and O2 +) scavenging ability of three structurallyrelated flavonoids (7-hydroxyflavanone HF, 2´,4´-dihydroxychalcone DHC and 3,7-dihydroxyflavone DHF) present ...
Experimental and Theoretical Study of the Stability of the Complex Fisetin–Cu(II) and A Comparative Study of Free Ligand and Complex Interaction with Molecular Singlet Oxygen
(Wiley Blackwell Publishing, Inc, 2020-07)
In this work, the flavonol fisetin was selected in order to study its reactivity against Cu(II), a metal ion of interest in biological media and industry. The stoichiometry and apparent formation constant of the complex ...
Quantum yields of singlet molecular oxygen, O2( 1Δg), produced by antimalaric drugs in organic solvents
(2003)
Detection of singlet molecular oxygen, O2(1Δ g), by phosphorescence emission, λ = 1270 nm, following laser excitation was employed to measure the quantum yield of O2( 1δg) generation by the antimalaric drugs quinine, ...
Solvent effects on reactions of singlet molecular oxygen, O-2((1)triangle(g)), with antimalarial drugs
(ELSEVIER SCIENCE SA, 2004-11-01)
Detection of O2(1 g) emission, λmax = 1270 nm, following laser excitation and steady-state methods were employed to measure
total reaction rate constants, kT, for the reaction between singlet oxygen and the antimalarial ...
