Quantum dot solids: This generation's silicon wafer?

Just as the single-crystal silicon wafer forever changed the nature of electronics 60 years ago, a group of researchers is hoping its work with quantum dot solids - crystals made out of crystals - can help usher in a new era in electronics.

Immune cells don't always ward off carbon nano invaders

Scientists have found evidence that some carbon nanomaterials can enter into immune cell membranes, seemingly going undetected by the cell's built-in mechanisms for engulfing and disposing of foreign material, and then escape through some unidentified pathway.

Physicists promise a copper revolution in nanophotonics

Researchers have proved that copper nanophotonic components can operate successfully in photonic devices - it was previously believed that only gold and silver components have the required properties for this. It means that light-based computers are closer to reality than ever before - copper is cheaper than gold or silver.
