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 ...

After discovery of fullerenes there were offered a wide variety of ways of their practical use. Nowadays a lot of patents in the field of fullerene chemistry concern use of fullerenes and nanotubes in semiconductor and nanoeletronic devices, e.g. photodiodes, transistors, sun batteries. Due to high electronegativity, fullerene C60 can easily form charge-transfer complexes in which it acts as ac...

Amphiphilic γ-cyclodextrin–fullerene 2:1 complexes (C L FC H complexes) were prepared by high-speed vibration milling of lipophilic tail-grafted γ-cyclodextrin (γ-CD), hydrophilic γ-CD and fullerene C 60 . The transamidation γ-CD–fullerene complex having two...

In this work, we report the functionalization of flat Si(100) surfaces with a calix[8]arene derivative through a thermal hydrosilylation process, followed by docking with [60]fullerene. Chemical grafting of calix[8]arene on silicon substrates was evaluated by X-ray photoelectron spectroscopy, whereas host-guest immobilization of fullerene was demonstrated by atomic force microscopy and sessile ...

  Purpose: To evaluate the effect of fullerene on chemical properties of naphazoline drug in   water by density functional theory (DFT) methods.   Materials and Methods: Naphazoline belongs to the imidazoline class of sympathomimetics.   The present study on naphazoline drug and its fullerene connected form were carried out using   computerized calculations of Gaussian program in b3lyp/6-31g le...

To elucidate important parameters for in vitro toxicity assessment of C(60) and C(70) fullerene colloidal particles, experiments were carried out in culture medium using pulsed field gradient nuclear magnetic resonance (PFG-NMR), asymmetrical flow field-flow fractionation (AFFFF), and dynamic light scattering (DLS) methods. First, the amounts of total and bulk bovine serum albumin (BSA) molecul...

Mass-selected beams of endohedral fullerene Ce@C82 ions, of atomic Ce q+ ions (q=2,3,4), and of empty fullerene-cage C82 ions were employed to study photoionization of fullerene-encapsulated and free cerium atoms. The Ce 4d inner-shell contributions to single and double ionization of the endohedral Ce@C82 fullerene have been extracted from the data and compared with expectations based on theory...

A database has been derived from recently reported [60]fullerene derivatives, and their binding scores with HIV-1 PR have been computed using docking techniques. Computational methods have been used to predict which derivatives may have high binding affinities, and for these compounds biological tests have been performed with purified PR. Experimental results confirm the high binding scores of ...

We examine the ultrafast dynamics of exciton migration and polaron production in sequentially processed 'quasi-bilayer' and preblended 'bulk heterojunction' (BHJ) solar cells based on conjugated polymer films that contain the same total amount of fullerene. We find that even though the polaron yields are similar, the dynamics of polaron production are significantly slower in quasi-bilayers than...

In this work, we have studied the antioxidant activity of fullerene C60 towards OH free radicals, using quantum chemistry and computational kinetics methods. Energy profiles are calculated using different basis sets, and reaction rate constants are reported for the first time. The reaction rate constant for the addition of the OH radical to the fullerene C60 is reported for the first time. A va...
