Glowing carbon nanotubes could sniff out the DNA signatures of bioterrorism agents

Carbon nanotubes have already found many valuable applications in nanotechnology. Now researchers are adding yet another potential use for these unique nanomaterials: as a detector for specific sequences of DNA. The work suggests that carbon nanotubes could be the basis for ultrasensitive devices for detecting pathogens such as anthrax and DNA mutations that cause genetic diseases, as well as leading to a more precise tool for understanding genetic mechanisms inside cells.
