Massachusetts Institute of Technology researchers have developed a "nano-printer" technique for mass-producing nano-devices.
The method, supramolecular nano-stamping, involves individual strands of DNA that can assemble themselves on a surface in any pattern, duplicating an original design. Each duplicate pattern can then be used as a master pattern.
The MIT team believes the clearest current use for the technology is in the production of DNA microarrays, nano-devices used to diagnose genetic problems such as Alzheimers disease and other illnesses.
