Spin-polarized currents can drive the motion of magnetic domain walls. Now, imaging studies show how the shape of domain walls evolve as they move along a ferromagnetic nanowire

A new simple method permits the growth of vertically aligned iron oxide haematite nanowires with potential applications in magnetic storage media

Composites of enzymes and single-walled carbon nanotubes can efficiently prevent protein contamination

Decorating arrays of polystyrene microspheres with carbon nanotubes recreates the lotus leaf’s self-cleaning ability

By coating a nanotube with a molecular layer that is thicker on one end than the other, it is possible to control the direction of heat conduction along the tube

With more than 350 nanoproducts already on the market, it is time for a programme of research that fully addresses concerns about the safety of nanotechnology.

Short single-walled carbon nanotubes can be grown longer using iron catalysts docked at each end

DNA strands containing artificial bases can be used to make chains of metal ions with defined sequences

Inorganic nanoribbons can be attached to an elastic surface at selected positions to make wave-like structures that maintain their semiconducting properties when stretched or compressed. These nanostructures will prove to be immediately useful in flexible electronics.

With high-resolution transmission electron microscopy, it is now possible to explore to what extent the random distribution of atomic elements in an alloy is preserved when it is reduced to a linear atomic chain, one atom thick.
