(PhysOrg.com) -- DNA is more than just a carrier for our genetic information; DNA is also an outstanding nanoscale building material, as researchers led by Ned Seeman discovered thirty years ago. Seeman and his colleagues at the New York University (USA) have now used cross-shaped DNA tiles to produce an amazingly large grid structure that resembles woven fabric. As the researchers report in the journal Angewandte Chemie, these two-dimensional crystals attain dimensions of about 2x3 micrometers.
