'Molecular hopper' can transport, manipulate single strands of DNA

Science
Aug. 31 (UPI) -- Scientists have designed a molecular machine -- a "molecular hopper" -- capable of moving single strands of DNA. The hopper moves along a nanoscale track. Its locomotion is made possible by the making and breaking of simple chemical bonds. In lab tests, the hopper successfully carried single strands of DNA through a protein nanotube. The breakthrough could inspire the next generation of gene editing technologies. "Being able to control molecular motion is the holy grail of building nanoscale machines," Hagan Bayley, a professor of chemistry at Oxford University, said in a news release. "Being able to process single molecules of DNA under precise chemical control may provide an alternative to the use of enzymes in DNA sequencing technologies, improving their speed and the ...
