To characterize fullerenes (C(60) and C(70)) as photosensitizers in biological systems, the generation of active oxygen species, through energy transfer (singlet oxygen (1)O(2)) and electron transfer (reduced active oxygen radicals such as superoxide anion radical O(2)(-)* and hydroxyl radical *OH), was studied by a combination of methods, including biochemical (DNA-cleavage assay in the presence of various scavengers of active oxygen species), physicochemical (EPR radical trapping and near… Expand
Synthesis of decacationic [60]fullerene decaiodides giving photoinduced production of superoxide radicals and effective PDT-mediation on antimicrobial photoinactivation.
We report a novel class of highly water-soluble decacationic methano[60]fullerene decaiodides C60[>M(C3N6(+)C3)2]-(I(-))10 [1-(I(-))10] capable of co-producing singlet oxygen (Type-II) and highlyExpand
The scavenging of reactive oxygen species and the potential for cell protection by functionalized fullerene materials.
The observed differences in free radical-scavenging capabilities support the hypothesis that both chemical properties, such as surface chemistry induced differences in electron affinity, and physical properties,such as degree of aggregation, influence the biological and biomedical activities of functionalized fullerenes.

Comparative photoactivity and antibacterial properties of C60 fullerenes and titanium dioxide nanoparticles.
Bacterial toxicity tests suggest that, unlike nano-TiO2 which was exclusively phototoxic, the antibacterial activity of fullerene suspensions was linked to ROS production, and fullerol and PVP/ C60 may be useful as water treatment agents targeting specific pollutants or microorganisms that are more sensitive to either superoxide or singlet oxygen.

Biomedical potential of the reactive oxygen species generation and quenching by fullerenes (C60).
The mechanisms and biological consequences of ROS generation/quenching by C60 are analyzed, focusing on the influence that different physico-chemical alterations exert on its ROS-related biological behavior. Expand
Water-soluble fullerene materials for bioapplications: photoinduced reactive oxygen species generation.
The photoinduced reactive oxygen species (ROS) generation from several water-soluble fullerenes was examined and efficient (1)O(2) generation was detected from photoexcited C(60), not only in organic solvents, but also in aqueous media and especially from small molecule C( 60)-carboxylic acid derivatives.

Mechanism of C60 photoreactivity in water: fate of triplet state and radical anion and production of reactive oxygen species.
This finding suggests that C60 clusters will not contribute to oxidative damage or redox reactions in natural environment and biological systems in the same way molecular C60 in organic phase reportedly does. Expand
Reaction of water-soluble fullerenes with O2˙− and other reactive radical species
In this work we focused on the reaction of water-soluble fullerene derivatives with various organic (i.e., methyl radical and t-butyl radical) and inorganic (i.e., superoxide radical and azideExpand
C60 Fullerol promoted Fe(III)/H2O2 Fenton oxidation: Role of photosensitive Fe(III)-Fullerol complex
Abstract Hydroxylated C60 Fullerene (Fullerol) induced photochemical production of reactive oxygen species (ROS, e.g. singlet oxygen (1O2) and hydroxyl radical (•OH)) is a slow process, and the roleExpand
Visible Light Sensitized Production of Hydroxyl Radicals Using Fullerol as an Electron-Transfer Mediator.
It is demonstrated that fullerol can mediate the electron transfer from Rhodamine B dye to O2 under visible light irradiation, achieving simultaneous dye decolorization and •OH-induced degradation of 4-chlorophenol. Expand
Pristine (C60) and hydroxylated [C60(OH)24] fullerene phototoxicity towards HaCaT keratinocytes: type I vs type II mechanisms.
The results clearly show that the phototoxicity induced by (gamma-CyD) 2/C 60 is mainly mediated by singlet oxygen with a minor contribution from superoxide, while C 60(OH) 24 phototoxic is mainly due to superoxide. Expand
