First discovered in 1975, carbon nanotubes are graphene sheets rolled up into cylinders. The diameter is typically in the nanometer range, and the length can be up to many micrometers. Carbon nanotubes offer promise in many applications, including electronics, novel materials, and medicine.  Now, researchers from Rice University have developed a spectral triangulation system, intended to pinpoint cancer tumours tagged with antibody-linked carbon nanotubes.  The … Continue reading Nanotubes light-up 3D location of cancer tumour.
