1 2 As the interest in the use of fullerene compounds in biomedical and cosmetic applications 3 increases, so too does the need to develop methods for their determination and quantitation in such 4 complex matrices. In this work we studied the behavior of C60 and C70 fullerenes in non-aqueous 5 capillary electrophoresis, as well as two C60 fullerene derivatives not previously reported by any 6 ...

A well-defined poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA-b-C60) was synthesized using the atom transfer radical polymerization (ATRP) technique and betainized with 1,3-sulfobetaine to yield a Bet-PDMAEMA-b-C60. The solution properties were then studied by light transmittance, viscometric, 1H NMR laser light scattering, and transmission electron macroscopic techniques. It was found that...

The self-assembly of molecules into complex superstructures underpins the functionality many biological processes and physical materials. Many such structures stem from amphiphilic monomer units, with attractions repulsions between their ends determining structure state assembled system under equilibrium, which affect its function. photophysical electronic properties fullerene (C60) have been e...

the spectroscopic properties of the 2,2,6,6-tetramethyl-piperidine-1-oxyl (tempo) radicalderivatives of the fullerene (c60) were theoretically investigated. the ground state optimizedstructures of the radical adducts of the fullerene were calculated by using dft (b3lyp) with 6-31g(d) level. it was concluded that a 6-6 ring junction of c60 moiety generally covalently links to thepiperidine ring ...

This study examines the biological effects of water-soluble fullerene aggregates in an effort to evaluate the fundamental mechanisms that contribute to the cytotoxicity of a classic engineered nanomaterial. For this work we used a water-soluble fullerene species, nano-C60, a fullerene aggregate that readily forms when pristine C60 is added to water. Nano-C60 was cytotoxic to human dermal fibrob...

Background and Objective: Occurrence of oxidative stress in uncontrolled diabetes mellitus affects spermatogenesis and the testicular functions. As the promising antioxidant activities of fullerene C60 nanomaterial have been demonstrated by previous reports, the current study aimed to determine the fullerene C60 effects on the markers of oxidative stress damage in testes of streptozotocin-induc...

Several dimerization products of fullerene C60 are presented and thoroughly characterized with a quantum chemical DFT model augmented by dispersion. We reanalyze expand significantly the number known dimers from 12 to 41. Many novel bonding schemes were found analyzing more than 2 ns high energy molecular dynamics semiempirical trajectories AutoMeKin, methodology previously used compute reactiv...

Herein, we detail how to grow one crystalline organic semiconductor on another epitaxially and thereby provide a method to tune the electronic nature of the p–n junction in organic photovoltaics (OPVs). While OPVs are attractive as materials for conversion of sunlight into electrical energy, higher conversion efficiencies are needed for OPVs to become a viable technology. Regardless of the type...

The hypothesis that C60 fullerene nanoparticles (C60) exert an antagonistic interactive effect on the toxicity of benzo[a]pyrene (BaP) has been supported by this investigation. Mussels were exposed to BaP (5, 50 & 100 ?g/L) and (C60–1 mg/L) separately in combination. Both shown co-localize secondary lysosomes hepatopancreatic digestive cells gland where they reduced lysosomal membrane stability...
