Scientists have developed exquisite control over the fabrication of carbon nanotubes, which can create among the blackest materials made by humans. Here, carbon nanotubes were fabricated on a surface to spell “50 um” (50 micrometers, millionths of a meter). The lines on each number and letter here are just 50 micrometers thick.
