DNA Computers
New research could one day help build computers from DNA. Scientists have found a way to ‘switch’ the structure of DNA using copper salts and EDTA (Ethylenediaminetetraacetic acid) — an agent commonly found in shampoo and other household products. The applications for this discovery include nanotechnology — where DNA is used to make tiny machines, and in DNA-based computing — where computers are built from DNA rather than silicon.
