Carbon nanotubes, a new member of the carbon material family, can be considered as graphite sheets rolled-up into cylinders with diameters ranging in the nanometer scale. In recent years, carbon nanotubes have attracted intensive interests because of their unique nanostructures and outstanding mechanical, electrical and magnetic properties. In this paper, the structures and basic features of carbon nanotubes were described in brief. The research advances in the carbon nanotubes on the specific recognition of biomolecules by surface modification and functionalization, in the enhancement to cell growth as culture scaffolds in vitro, and in the improvement of biocompatibility for implantable biomedical material were reviewed. Also comments were made on their potential applications in biomedical sensor and biomedical microelectrics.
碳纳米管是碳材料家族的新成员，可被视为由直径在纳米尺度范围内的石墨片卷曲而成的圆柱体。近年来，碳纳米管因其独特的纳米结构以及出色的机械、电学和磁学性能而引起了广泛关注。本文简要描述了碳纳米管的结构和基本特征。综述了碳纳米管通过表面修饰和功能化对生物分子进行特异性识别、作为体外培养支架促进细胞生长以及改善可植入生物医学材料生物相容性方面的研究进展。此外，还对其在生物医学传感器和生物医学微电子学中的潜在应用进行了评述。
