中文摘要：

采用L-半胱氨酸盐酸盐,通过化合接枝法对洋葱状富勒烯进行功能化,合成水溶性L-半胱氨酸富勒烯衍生物。利用扫描电子显微镜（SEM）、X射线衍射（XRD）、红外光谱（IR）、热重分析（TGA）及X射线能谱分析（XPS）对所制样品进行表征。结果表明：L-半胱氨酸富勒烯衍生物表面具有-OH、-NH3等亲水性基团,水溶性良好。裸鼠实验表明,合成的L-半胱氨酸富勒烯衍生物在生物体组织细胞中具有很好的分布,可以顺利溶入生物体体液并具备良好的流动性。

英文摘要：

Water-soluble onion-like fullerene（OLF）derivatives were prepared by chemical bonding of L-cysteine,an important amino acid in organisms,to OLFs.The L-cysteine OLFs were characterized by SEM,XRD,IR,TGA and XPS.Results showed that hydrophilic groups added to the surface of OLFs such as-OH and-NH3 made L-cysteine OLFs good water-soluble derivatives.Experiments in mice demonstrated that the water-soluble fullerene derivatives were well distributed in the histolytic organism because of their excellent solubility and fluidity in humoral liquid.
