Researchers discover new properties of world's thinnest material

Researchers have studied graphite oxide for years and have discovered how to assemble these soft sheets like floating water lilies pads. They also used a camera flash to turn them into graphene, and invented a fluorescence quenching technique to make them visible under microscopes.

How bacteria make nano-syringes

For a successful infection, bacteria must outwit the immune system of the host. To this aim, they deliver so-called virulence factors through a transport channel located in the bacterial membrane. In some bacteria this transport channel is formed like a syringe, enabling them to inject virulence factors directly into the host cell. Scientists have now succeeded for the first time in elucidating basic principles of the assembly of this transport channel.
