Various types of lipid membrane-incorporated C60 with high C60 concentrations can be prepared easily in several hours using the C60 exchange method and the photocleaving activity of cationic lipid membrane-incorporated C60 was appreciably higher than that of the C60.gamma-CDx complex.

In this work, the doping of n-layer graphenes with C60 is investigated via Raman spectroscopy. The results indicate that C60 can induce hole doping in graphenes, and that the doping level is closely related to the layer number of the graphenes. Moreover, the level of doping in the hybrid of C60 on graphene (C60/G) is more significant than that in the hybrid of graphene on C60 (G/C60).

The successful synthesis of H2O@C60 makes possible the study of magnetic interactions of an isolated water molecule in a geometrically well-defined hydrophobic environment. Comparisons are made between the T1 values of H2O@C60 and the previously studied H2@C60 and their nitroxide derivatives. The value of T1 is approximately six times longer for H2O@C60 than for H2@C60 at room temperature, is i...

We have created insulated C60 nanowire by packing C60 molecules into the interior of insulating boron nitride nanotubes (BNNTs). For small-diameter BNNTs, the wire consists of a linear chain of C60 molecules.With increasing BNNT inner diameter, unusual C60 stacking configurations are obtained (including helical, hollow core, and incommensurate) that are unknown for bulk or thin-film forms of C6...

The behavior of intermolecular interactions in fresh and aged solutions fullerene C60 neat N-methyl-2-pyrrolidone (NMP), as well NMP/xylene mixed solvents, were studied by the methods ultraviolet-visible spectroscopy dynamic light scattering (DLS). It has been experimentally shown that aging C60/NMP solution leads to disappearance characteristic maximum molecular absorption at ∼330 nm with smoo...

A new class of water-soluble C60 transfecting agents has been prepared using Hirsch-Bingel chemistry and assessed for their ability to act as gene-delivery vectors in vitro. In an effort to elucidate the relationship between the hydrophobicity of the fullerene core, the hydrophilicity of the water-solubilizing groups, and the overall charge state of the C60 vectors in gene delivery and expressi...

We report the preparation and single-molecule observation of a high molecular weight C60-end-capped, stereoregular poly(methyl methacrylate) (PMMA-C60) with a precisely controlled structure. The highly isotactic PMMA-C60 (mm = 98%) with a narrow molecular weight distribution was synthesized by the stereospecific anionic living polymerization of tert-butyl methacrylate followed by end-capping wi...

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...
