Strengthening nanotube fluorescence

In a way, nanotubes are nature's smallest candles. These tiny tubes are constructed from carbon atoms and they are so small that it takes about 100,000 laid side-by-side to span the width of a single human hair. In the last five years, scientists have discovered that some individual nanotubes are fluorescent.
