Nanodevice manufacturing strategy using DNA 'Building blocks'

      Wyss researchers have built

numerals,letters and
a number of other structures 
using short strands
of DNA as building blocks.

Researchers have developed a method for building complex nanostructures out of interlocking DNA "building blocks" that can be programmed to assemble themselves into precisely designed shapes. With further development, the technology could one day enable the creation of new nanoscale devices that deliver drugs directly to disease sites.

DNA is best known as a keeper of genetic information. But in an emerging field of science known as DNA nanotechnology, it is being explored for use as a material with which to build tiny, programmable structures for diverse applications. To date, most research has focused on the use of a single long biological strand of DNA, which acts as a backbone along which smaller strands bind to its many different segments, to create shapes.
