Washington, Jan 24 (ANI): Researchers have now constructed a DNA motor that is capable of running along a programmable network of tracks with multiple switches.
A team at Kyoto University and the University of Oxford manipulated DNA with a technique called "DNA origami."
Just like its paper counterpart, this method uses DNA to fold structures into two and three dimensions. The folding of the molecules is done via sequencing in such a way that the DNA naturally self-assembles into the desired shape. The tiny tracks were laid down on top of tiles, also made of DNA, the Discovery News reported.
Since it is feasible to program the way the tracks are laid down, the whole system can carry information the same way electrons do in a computer's circuits. Basically it is a DNA-powered computer.
"We are really still at an early stage in designing DNA origami-based engineering systems," said Integrated Cell-Material Sciences Professor Hiroshi Sugiyama, in a statement.
"The promise is great, but at the same time there are still many technical hurdles to overcome in order to improve the quality of the output," Sugiyama added.
The new innovation could prove to be a good method for building structures at the molecular scale. The programmability of the switches implies that now one can give a certain set of inputs and get the expected output, which is the basis for any manufacturing. Such a programmable DNA system might also make a good sensor.
The work has been recently published in Nature Nanotechnology. (ANI)
