Immunotoxicity studies of nanoparticles on T cells addressed their effects on activation by T antigen receptor, but have neglected the regulation of proliferation by IL-2. In this study, the IL-2-dependent T lymphoblastoid WE17/10 cell line was used to compare silver (Ag-NPs) and fullerene (C60-NPs) nanoparticles' toxicity and evaluate whether these NPs could interfere with IL-2-dependent proli...

Atomistic molecular dynamics simulations are performed for up to 20 ns to monitor the formation and the stability of complexes composed of single- or double-strand DNA molecules and C60 in aqueous solution. Despite the hydrophobic nature of C60, our results show that fullerenes strongly bind to nucleotides. The binding energies are in the range -27 to -42 kcal/mol; by contrast, the binding ener...

Growth experiments of transplanted malignant tumors in the presence of water-soluble C60 fullerenes were performed on groups of mice. It was found that C60 fullerenes efficiently inhibit the growth of transplanted malignant tumors. This behavior can be explained through their high antioxidant activity and the blocking of the specific cell receptors (for example, endothelial growth factor). The ...

The reaction of the tetrakis[di(ethoxycarbonyl)methano]-C60 (1) with Ru3(CO)12 afforded the first bis-parallel C60-metal cluster complex: parallel-[Ru3(CO)9]2{μ3-η(2),η(2),η(2)-C60[C(COOC2H5)2]4}. The two triruthenium groups are found in either a parallel or a tilted orientation relative to each other, as determined by NMR. Only the parallel form was characterized by X-ray crystallography.

Binding of a porphyrin carboxylate anion () to tetrathiafulvalene calix[4]pyrrole (TTF-C4P) results in electron transfer from TTF-C4P to Li(+)@C60 to produce the charge-separated state (1/TTF-C4P˙(+)/Li(+)@C60˙(-)) in benzonitrile. Upon photoexcitation of , photoinduced electron transfer from the triplet excited state of to TTF-C4P˙(+) occurs to produce the higher energy charge-separated state ...

Fullerene-C60 (C60) is mainly applied in the aqueous phase by wrapping with water-soluble polymer or by water-solublizing chemical-modification, whereas C60 dissolved in oil is scarcely applied; still less explicable is its toxicity.We dissolved C60 in squalane at near-saturated or higher concentrations (220-500 ppm), named LipoFullerene (LF-SQ),and examined its biological safety. LF-SQ was adm...

We propose an evaluation C60:C60+ ratio diffuse translucent exploits electronic absorption bands so as not to rely on ambiguous IR emission measurements. Methods. The determined by analyzing archival spectra literature data. In...

As a newly synthesized two-dimensional carbon material, the stability study of monolayer fullerene networks or quasi-hexagonal phase fullerenes (qhp-C60) is timely desirable. We have investigated stabilities qhp-C60, including thermal, structural, mechanical, and thermodynamic stabilities, as well bonding characteristics, ductility, mechanical properties, via first-principles calculations. The ...
