Carbon nanotube array senses DNA

Abstract:
Scientists at the NASA Ames Research Center, US, have developed an array of multiwalled carbon nanotubes that can detect low levels of DNA. An array just 20 m square can detect less than one million copies of target oligonucleotide, a sensitivity comparable to laser-based fluorescence techniques.
