摘要： The present invention relates to a carbon nanotube transistor biosensor with aptamers and a method for detecting a target material using the same, more particularly to a carbon nanotube transistor biosensor recognizing the target material, i.e., a specific molecule (such as a protein, a peptide, an amino acid, and an organic/inorganic compound) by using DNA aptamers and a method for screening a target material using the same. In the biosensor of the present invention, the aptamers binding specifically to a particular protein are adsorbed on a carbon nanotube constituting the channel domain of carbon nanotube transistor to easily detect/identify a particular protein via the electric conductivity of carbon nanotube that varies if the particular protein is exposed to corresponding aptamers.

摘要： The present invention relates to a method of manufacturing a carbon nanotube transistor in which a carbon nanotube channel is formed between a source electrode and a drain electrode and a gate electrode is formed at one side of the carbon nanotube channel, the method comprising the steps of: (a) forming the carbon nanotube channel on a substrate; (b) electrically connecting the source electrode and the drain electrode to both ends of the carbon nanotube channel, respectively; and (c) applying a stress voltage across the source electrode and the drain electrode to remove metallicity of the carbon nanotube channel.According to the method of manufacturing a carbon nanotube transistor of the present invention, a metallic part can be selectively removed from a carbon nanotube which is used as a channel of a transistor and has metallic properties and semiconductor properties mixed with each other.
