Which two elements are nanowhiskers usually made of?

Nanowhiskers are tiny threads that measure about 10 nano- meters (1 nm = 0.000000001 m) in length and 1.5 nanometers in diameter. They are often made of carbon or silver. Scientists have found that the carbon-based material that makes up the structure of a sea squirt, shown in Figure 1, is made of nano- whiskers.

hope this helps
