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…
