Artificial molecules
Artificial molecules
A new method allows scientists at ETH Zurich and IBM to fabricate artificial molecules out of different types of microspheres. The researchers would like to one day use such tiny objects in micro-robots, for photonics and basic biochemical research. Scientists at ETH Zurich and IBM Research Zurich have developed a new technique that enables for the first time the manufacture of complexly structured tiny objects joining together microspheres.

Graphene nanoribbons: it’s all about the
As reported by the journal Nature in its latest issue, researchers from Empa, the Max Planck Institute in Mainz and the Technical University of Dresden have for the first time succeeded in producing graphene nanoribbons with perfect zigzag edges from molecules. Electrons on these zigzag edges exhibit different (and coupled) rotational directions ("spin").

"Swiss army knife" molecule
Scientists at ETH Zurich and an ETH spin-off have developed a novel polymer for coating materials, in order to prevent biofilms from forming on their surfaces.

Cancer: banana peels can help identify the stages of melanoma
Cancer: banana peels can help identify the stages of melanoma
08. Human skin and banana peels have something in common: they produce the same enzyme when attacked. By studying fruit, researchers have come up with an accurate method for diagnosing the stages of this form of skin cancer. When bananas age they become covered in black spots caused by the enzyme tyrosinase.

Copper deposition to fabricate tiny 3D objects
Copper deposition to fabricate tiny 3D objects
A new 3D microprinting process allows scientists to easily manufacture tiny, complex metal components. The used technology was designed by ETH researchers years ago for biological research and has now been further developed for a completely different application. Scientists at ETH Zurich have developed a new method of 3D microprinting.

A super-fine solution to sponge up micropollutants
A super-fine solution to sponge up micropollutants
07. A super-fine form of powdered activated carbon captures micropollutants more rapidly than the conventional kind and could by used in Swiss wastewater treatment plants, say EPFL researchers in a new study. Even at extremely low concentrations, micropollutants - trace amounts of chemical compounds from pharmaceutical or agricultural chemicals - can pose a risk to aquatic ecosystems.

Nanowalls for smartphones
Nanowalls for smartphones
Researchers at ETH Zurich have manufactured transparent electrodes for use in touchscreens using a novel nanoprinting process. The new electrodes are some of the most transparent and conductive that have ever been developed. From smartphones to the operating interfaces of ticket machines and cash dispensers, every touchscreen we use requires transparent electrodes: The devices' glass surface is coated with a barely visible pattern made of conductive material.
