Electronics from a printer - of electronic radio tags and lighting wallpapers

Glucose meters and the appropriate test strips for diabetics are expensive. This however might change, since scientists at the Institute of Printing Science and Technology (IDD) at TU Darmstadt are working on a sensor making the electronic devices considerably cheaper. The new sensor is not based on silicon as conducting material, but on plastics.

Chemists use graphene to visualize atomic-scale structures

Researchers at the California Institute of Technology (Caltech) have devised a new technique - using a sheet of carbon just one atom thick - to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules.
