Scientists have struggled for over thirty years to market a DNA computer to the masses. It can play tic-tac-toe and solve the Traveling Salesman Problem (best way for a national sales guy to visit twenty-thirty cities–quite relevant to everyday people). Now the experts are considering using DNA computer apps to fight disease. But, for us middle Americans, we are far from benefiting from the power, affordability and tiny size of DNA computers.
Here’s a clever idea I stumbled across on MIT’s blog. We all know that the reason the brain can do so much is it relies on the folds that cover its surface. Technically, they’re not ‘folds’; they’re Gyri or Gyrus (singular) and the ‘valleys’ between the Gyri are called Sulci or Sulcus. Anyway, Mother Nature added these to give that umph to our brains in power, storage capacity and speed that no computer comes close to matching. Why not add them to DNA computers? Here’s a discussion:
Using DNA structures, researchers may be able to construct tinier, cheaper chips
Artificial, self-assembling DNA structures may help make smaller and cheaper microchips, according to research presented in the latest issue of Nature Nanotechnology. Tinier microchips would allow faster computers and other electronics.
Researchers from IBM and the California Institute of Technology used a technique known as DNA origami, where a long strand of DNA is folded into a shape with many shorter strands dubbed staples, creating a three-dimensional shape. In the paper, the researchers demonstrated using DNA origami-shapes as a scaffold for carbon nanotubes–a trick that could eventually be used to create nanoscale microchips.
The DNA structures are tiny enough to have features measuring six nanometers–the current industry standard for microchips is 45 nanometers. The process could replace the expensive tools manufacturers currently use to make tiny chips, although IBM suggests that it could take up to 10 years to test and refine the process for manufacturing.
