Abstract

The present invention relates an apparatus to separate carbon nanotubes by their electrical conductivity. Known production processes for single-walled carbon nanotubes produce a mixture of nanotubes with metallic and semiconductive electrical conductivities. Some potential applications require one conductivity or the other. The mixture may be undesirable. Carbon nanotubes of varying electrical conductivity may be separated by hybridizing the nanotubes with nucleic acids such as DNA and then passing a dispersion of the hybrids through an electrochemical cell with an electrical potential on the working electrode which absorbs or desorbs nanotubes of a desired electrical conductivity.
