Abstract:
Provided are a carbon nanotube composite containing a bridging agent, single-chain DNA and carbon nanotubes and a manufacturing method thereof. A carbon nanotube composite comprises: a carbon nanotube(30); single-chain DNA(10) adhering to the surface of the carbon nanotube; and a bridging agent bonded with the end of the single-chain DNA. The bridging agent represents biotin(20,22). The bridging agent can specifically bond with the specific molecule adhering to a biomolecule to be detected so as to couple the carbon nanotube composite with the biomolecular material. The biomolecule coupled with the carbon nanotube composite can be detected by spectroscopic analysis.
