Very small amounts of fluid can be precisely injected into cells using an electrochemical syringe

An array of electrodes made of carbon nanofibres can stimulate and record electrical activity from slices of a mouse brain

Molecular dynamics simulations suggest that the pumping rates of nanoscale molecular propellers vary depending on the properties of their blades

An ordered array of silicon–germanium shells shows enhanced light emission compared with an unpatterned sample

A new stable and continuous nanosized laser could revolutionize optical electronics

By attaching a range of chemically modified nanoparticles to a microfabricated array of tipless cantilevers, large combinations of chemical interactions can be measured

The chemical reactivity of organic molecules can be reduced significantly by confining them inside carbon nanotubes

A non-volatile memory device based on the relative magnetization direction of two ferromagnetic semiconducting nanobars has been demonstrated

Two-dimensional arrays of living bacteria have been printed on substrates with single-cell resolution

A new approach to making a biosensor with a field-effect transistor provides high sensitivity with simple processing by introducing a vertical nanogap into the device structure.

When involving the public in discussions about new developments in science and technology, there are important differences between nanotechnology and other areas that need to be taken into account, as Chris Toumey explains.

High-resolution images of shape changes in retinal — a molecule that plays a key role in vision — allow us to see what happens when we see.

Water contracts when it is cooled but, unlike other liquids, it then starts to expand at temperatures a few degrees above the melting point of ice. However, a new experimental study suggests that normal behaviour returns if the water is supercooled to low enough temperatures.

The scientific output of the Asia–Pacific region is growing, especially in nanoscience and technology, but there is scope for greater collaboration and networking between researchers.
