Scientists create nano-pipes that are two million times smaller than an ant

 

Researchers at the Johns Hopkins Whiting School of Engineering have developed microscopic leak-free pipes using DNA strands. The diameter of each DNA pipe or nanotube is only about 7 x 10^-9 m and has a length almost similar to that of a dust particle. Despite being so small, the nano pipes have great potential as they could be used in the future to study complex diseases and deliver drugs directly to human body cells.
