ResumoSingle-walled carbon nanotubes (SWNTs) were covalently functionalized with biocompatible poly-l-lysine, which is useful in promoting cell adhesion. SWNTs played an important role as connectors to assemble these active amino groups of poly-l-lysine, which provided a relative "friendly" and "soft" environment for further derivation, such as attaching bioactive molecules. As an application example, by further linking peroxidase, an amplified biosensing toward H2O2 concerning this assembly was investigated.
