Researchers demonstrate the performance of a new nanoprinting technique

Scientists at the IBM Research Laboratory in Zurich in collaboration with the ETH Zurich have succeeded in placing so-called nanotubes - only 25 x 80 nanometers - on a surface in a highly precise and systematic way using a special nanoscale orientation and a printing process that allows them to print any arbitrary pattern with individual particle resolution. To show that their method works, the scientists constructed the pictogram of a standing pedestrian walking like the one in traffic lights from selectively oriented gold nanotubes. An interesting application for this method could be checking the authenticity of valuable objects such as watches, jewelry or works of art.

The scientific journal Advanced Functional Materials included an article in its February 22, 2012 issue describing this work.

The publication describes how this method even allows oblong nanotubes to be oriented specifically in the same direction - longitudinally or transversely - while preserving the often unique properties of the nanotubes.
