A combination of two lasers can efficiently drive an ultrafast current pulse in a molecular circuit

Non-functionalized carbon nanotubes can transform the shape of quantum dots

A flat organic molecule resting on a surface can be reversibly switched between two different conductance states with an STM tip

A scanning tunnelling microscope can be used to observe and control the magnetic properties of single atoms on a surface

A solution-phase synthesis process allows SnTe nanocrystals to be fabricated with tunable bandgap energies that can range down to the mid-infrared

Adding a small amount of manganese to cadmium sulphide nanocrystals can generate a stable shade of white light

Crescent-shaped gold nanostructures have optical properties that can be tuned into the visible portion of the light spectrum, with promising applications in biosensing

The strong interaction between the light confined to the surface of a nanowire and an optical emitter is the basis for a single-photon transistor

Periodic nanostructures can be made over large areas using a simple low-cost method in which a thin polymer film is sandwiched between two flat plates that are then pulled apart.

As companies rush to bring new products to market, they may be cutting corners in ways that will backfire on them in the future. Spending more time on the early stages of the development process will, says Michael Helmus, save time later.

Gold nanoparticles are routinely used as 'seeds' to grow semiconductor nanowires and it has now been discovered that the nanowires grow faster when the gold seeds are placed closer together.

A nanoscale superconducting device in which the flow of heat can be switched on and off by a gate voltage — a heat transistor — has been demonstrated at temperatures close to absolute zero.

Most definitions of nanotechnology focus on the control of matter, not light, but research in nanophotonics is thriving in areas as diverse as quantum optics and biological imaging.

Uncertainties in new regulations that cover the manufacture, importation and production of chemicals in the European Union could make it more difficult to commercialize nanotechnology.
