Roland Piquepaille writes "Japanese researchers have found a way to build long threads of DNA using miniaturized hooks and bobbins. In fact, they've demonstrated how to manipulate delicate DNA chains without breaking them. They've designed these laser-directed microdevices to pick up and manipulate individual molecules of DNA. The scientists have used optical tweezers to catch and move these microdevices, which could be used in the future to detect genetic disorders such as Down's syndrome. But read more for additional details and references, including diagrams showing the chromosomal DNA manipulation methods used by the scientists to build long DNA strands."
