Scientists Demo New Nanoprinting Tech with Microscopic Golden Olympic Logos

Illustration for article titled Scientists Demo New Nanoprinting Tech with Microscopic Golden Olympic Logos

Scientists at Northwestern University have demonstrated a new nano-printing technology by printing the Beijing Olympics emblem 15,000 times, each logo so small the whole print run fits inside one square centimeter. 2,500 of the images, made 20,000 90-nanometer dots, would fit on a grain of rice. The polymer pen lithography uses an array of millions of tiny flexible polymer "pens" that can be used to make marks on various different nano-scales, and in this case deposit "ink" made of 16-mercaptohexadecanoic acid onto a gold substrate (what else would do, in Olympic season?) The team thinks that the technique, which can print out tiny dot-matrix imagery, will find uses in computational tools, medical diagnostics and the pharmaceutical industry. The study is published today in Science Express. [Physorg]

"Scientists at Norwestern University have demonstrated their new nano-printing technology...

Uh... it turns out the nano-printing technique was actually developed by scientists at MIT, but the Governing Board decided scientists from NU should be the ones to demonstrate it instead since the NU scientists were cuter than the ones from MIT.
