Itssurface morphologies and property were worked out by us-ing atomic force microscopy (AFM) and contact angle meas-urement. Moreover, the prime cytocompatibility was used to investigate the biocompatibility of the composite materialcontaining CNTs and the effects of CNTs on one aspect of cell function, cell affinity. The results obtained indicate that thecomposite material of PLLA and CNTs possesses good bio-compatibility for both the 3T3 fibroblasts and Oct-1 os-teoblast-like cells. The addition of CNTs will greatly affectcell affinity of the material, which may be disadvantage for the cell adhesion.展开更多

The clusters of fullerene derivative formed in mixed solvents are introduced into the channels of porous alumina templates through a dc electric field. Four types of 1D nanostructures (solid nanowires, solid-wall nanotubes, porous nanowires and porous-wall nanotubes) have been obtained by changing the deposition parameters. This approach opens a new avenue to assemble fullerene derivatives, endohedral fullerenes, as well as other functional organic compounds, which can form clusters in 1D nanostructure arrays for applications in chemical sensors, light energy conversion devices and nano- scale electronic and optoelectronic devices.展开更多
