Research on biological effects of C60 and its derivatives is one of the hotspots in the area of biological effects of nanomaterials. Compared with surface-modified C60 derivatives, reports on the biological effects of unmodified pristine C60 are relatively less. This work aimed to investigate the interaction between baby hamster kidney cells and pristine C60 in solution. The C60 suspension was ...

Fullerenes are widely produced and applied carbon nanomaterials that require a thorough investigation into their environmental hazards and risks. In this study, we compared the toxicity of pristine fullerene (C60) and carboxylated fullerene (C60-COOH) to white rot fungus Phanerochaete chrysosporium. The influence of fullerene on the weight increase, fibrous structure, ultrastructure, enzyme act...

Superconducting behavior even under harsh ambient conditions is expected to occur in La@C60 if it could be isolated from the primary metallofullerene soot when functionalized by CF3 radicals. We use ab initio density functional theory calculations to compare the stability and electronic structure of C60 and the La@C60 endohedral metallofullerene to their counterparts functionalized by CF3. We f...

Single crystals of three-dimensional (3D) C60 polymer were prepared by the topotactic conversion of two-dimensional (2D) C60 polymer single crystals at a pressure of 15 GPa at 600 degrees C. The x-ray single crystal study revealed that the 3D C60 polymer crystallized in a body centered orthorhombic space group Immm, and spherical C60 monomer units were substantially deformed to rectangular para...

The antitumor activity of pristine C60 fullerene aqueous solution (C60FAS) compared to 5-fluorouracil (5-FU) and pyrrole derivative 1-(4-Cl-benzyl)-3-Cl-4-(CF3-fenylamino)-1H-pyrrol-2.5-dione (MI-1) cytostatic drugs was investigated and analyzed in detail using the model of colorectal cancer induced by 1.2-dimethylhydrazine (DMH) in rats. The number, size, and location of the tumors were measur...

The interaction of C60 with single-wall carbon nanotubes (SWNTs) and graphite is studied experimentally by thermal desorption spectroscopy and theoretically by molecular-mechanics and molecular-dynamics calculations. The van der Waals parameters and force field for C60-graphene and C60-SWNT interactions are derived from the low-coverage C60 binding energy to the graphite surface. We use these t...

A giant amphiphile, which is constructed with an amorphous nano-pyramid (triphenylamine, TPA) and a crystalline nano-sphere (C60), was synthesized. Structural characterization indicates that this pyramid-sphere-shaped amphiphile (TPA-C60 ) forms a solvent-induced ordered phase, in which the two constituent units self-assemble into alternating stacks of two-dimensional (2D) TPA and C60 nano-shee...

While several recent reports have described the toxicity of water-soluble C60 fullerene nanoparticles, none have reported the toxicity resulting from the inhalation exposures to C60 fullerene nanoparticles or microparticles. To address this knowledge gap, we exposed male rats to C60 fullerene nanoparticles (2.22 mg/m3, 55 nm diameter) and microparticles (2.35 mg/m3, 0.93 microm diameter) for 3 ...

The design of multicomponent ionic complexes of fullerenes, (D1) (C60 ) (D2) is discussed. In this approach D1 was an organic cation and D2 was a neutral structure-forming molecule. These complexes demonstrated paramagnetic-diamagnetic transitions associated with the C-C and M-C bond formation, singlet-triplet transitions and high conductivity. 1. (D) (C60 ) CoOEP contain tetramethylphosphonium...
