Scientists at the IBM Research Laboratory in Zürich and ETH Zürich, Led by Dr. Heiko Wolf, have succeeded in positioning nanotubes on a surface in a highly precise and systematic manner using a special nanoscale orientation and printing process. The orientation and printing process allows one to print any arbitrary pattern with a resolution of individial particles onto a surface and even allows oblong nanotubes to be oriented specifically in the same direction - lengthwise or crosswise - while preserving the often unique properties of the nanotubes. To prove the capability of this new method, the scientists constructed a standing and a walking Ampelmännchen (pedestrian pictogram on traffic lights) of selectively oriented gold nanotubes. Observed through a polarization filter, the color of the light changes depending on the orientation of the gold nanotubes relative to the filter. In this manner the standing Ampelmännchen is red and the walking Ampelmännchen is green. The results have been published in Advanced Functional Materials. Read this and the 7 very interesting news below.

First Physical Metatronic Circuit Using Nanotechnology |
| A research team led by Nader Engheta from the University of Pennsylvania is working on ways to use light in place of electricity. The team has developed the first physical illustration of ‘lumped’ optical circuit elements using nanotechnology.

Solving A Spintronic Mystery |
| A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers have determined the origin of the charge-carriers responsible for the ferromagnetic properties that make gallium manganese arsenide such a hot commodity for spintronic devices.

Cells On Film As A Nanoscale Diagnostic Tool |
| Cancer cells that break free from a tumor and circulate through the bloodstream spread cancer to other parts of the body. But this process, called metastasis, is extremely difficult to monitor because the circulating tumor cells (CTCs) can account for as few as one in every billion blood cells.

Negative Refraction Opens Door To New Products And Industries |
| Researchers at Oregon State University have discovered a way to make a low-cost material that might accomplish negative refraction of light and other radiation – a goal first theorized in 1861 by a giant of science, Scottish physicist James Maxwell, that has still eluded wide practical use.

Hybrid Structures Show Improved Light Emission |
| New work on hybrid structures containing semiconductor quantum dots and metal nanoparticles could lead to better light-emitting diodes and help develop non-linear photonic devices in the future. The light emitted by the structures can be dramatically increased by simply tuning the surface plasmons on the gold particles to be in resonance with the exciton transitions in the quantum dots.
