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.
