Tiny cupid proof that BYU students love nanotechnology

Got a “little crush” on someone this Valentine’s Day? Maybe you’ve been hit by a little arrow belonging to this cupid made from carbon nanotubes by Brigham Young University physics students.

You don’t have to be a science lover to be amazed at how they build on such a small scale. First, they put a pattern of microscopic iron “seeds” onto a plate. A blast of heated gas causes a miniature forest of carbon nanotubes to spring up. Each nanotube measures about 20 atoms across and is 99 percent air.
