Taking ice lithography to the next level

Nanowerk.com - 14 декабря, 2017 - 22:28
Researchers have discovered that ices of simple organic molecules such as alcohols and nonane (main component of diesel) can be nanopatterned by a focused electron beam. The entire 3D lithography process takes place in a single vacuum instrument and avoids exposing users to chemicals and the need for cleanrooms. With organic ice resist (OIR) technology, nanolithography can be made accessible to more scientists. The short-term implication of this work is to provide researchers with a new nanoscale 3D printing technology. The long-term implications might have a revolutionary impact on semiconductor production and computing.

Spaghetti-like, DNA 'noodle origami' the new shape of things to come for nanotechnology

ScienceDaily.com: Nanotechnology News - 14 декабря, 2017 - 22:03
Scientists have invented a major new advance in DNA nanotechnology. Dubbed 'single-stranded origami,' their new strategy uses one long, thin noodle-like strand of DNA, or its chemical cousin RNA, that can self-fold -- without even a single knot -- into the largest, most complex structures to date. The strands forming these structures can be made inside living cells, opening up the potential for nanomedicine.
