Long thin iron oxide composites move back and forth when an external magnetic field is applied, mimicking the motion of cilia

Researchers have found a way to convert the vibration of a large array of nanowires into a stable electrical current

A nanoscale knife can precisely cut and sharpen carbon nanotubes

Gallium nanoparticles can be reversibly switched between four different structural phases with a laser, which could increase the data storage density in all-optical media

Carbon nanofibres have been used to make flexible all-plastic field-emission devices

A quantum-wire device could lead to a new definition of electric current

Indium oxide can be made into nanoarrows and other nanostructures by changing the catalyst and source materials used in a chemical vapour deposition approach

The conductance of metallic carbon nanotubes can be suppressed by reacting them with electron-deficient molecules

New measurements may settle a long controversy about what happens when water comes into contact with a hydrophobic surface

Researchers show how to control the morphology of self-assembled organic nanoparticles by tuning the geometry of the constituent molecules

Individual nanoparticles can be picked up and placed on a surface using dip-pen nanolithography

Researchers have made a miniature electrical switch by shifting the position of atoms on a surface with the tip of a scanning tunnelling microscope

Why do hundreds of companies and tens of thousands of people attend a nanotechnology conference in Tokyo every year? Adarsh Sandhu finds out.

Keeping drug-delivery vehicles in the bloodstream for a long time is a challenge. New results suggest that adopting the filamentous shape of viruses may lead to better nanocarriers.

Relatively little is known about how spins interact with an organic environment. Now, a study of organic nanowires shows that spin information is preserved over exceptionally long times.
