Researchers find technique for 3-D printing on nanoscale
that can correct mistakes

University of Dayton physics and electro-optics
researchers Md Shah Alam, Qiwen Zhan and Chenglong Zhao have
created a less expensive 3-D printing method on a nanoscale, or a
thousand times smaller than a human hair, that can manufacture
nanostructures and erase mistakes. Top nanotechnology journal Nano
Letters published their findings.
