Researchers develop stable silver wire that is just one atom wide

In a step towards the goal of shrinking electronic devices to the molecular scale, an international team of researchers has developed a stable silver wire that is just one atom wide.

How photoblueing disturbs microscopy

The latest developments in fluorescence microscopy make it possible to image individual molecules in cells or molecular complexes with a spatial resolution of up to 20 nanometres. However, under certain circumstances, an effect occurs that falsifies the results: the laser light used can cause very reactive oxygen molecules to form in the sample.
