Researchers construct a "molecular hopper", capable of moving single strands of DNA through a protein nanotube. The tiny hopper works by making and breaking in sequence simple chemical bonds that attach it to a nanoscale track. This might make it suitable for use in nanopore DNA sequencing devices.
