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.

With exciting new results appearing every week, graphene is one of the hottest topics in physics, and may also form the basis of a new approach to electronics a decade from now.

An innovative and scalable strategy for making high-density arrays of aligned nanotubes could lead to the mass-production of high-performance, high-power flexible electronics.

Nanotechnology will make it easier for governments and companies to invade the privacy of citizens and customers, warns Chris Toumey.

First isolated less than three years ago, graphene is currently the hottest topic in condensed-matter physics and materials science. Expect further breakthroughs in fundamental physics and, possibly, the advent of graphene-based electronics.

Numerous copies of a pumpkin-shaped molecule can be linked together to form a nanocapsule shell that can trap compounds inside. The outer surface of this capsule can be decorated with other species by plugging them into the cavities of the hollowed-out pumpkins.
