A team of engineers and physicists from Northeastern University in Boston has demonstrated a new technique of assembling nanotubes using gold.

The group, from the institution's Electronic Materials Research Institute, placed a 15-nanometre thick layer of gold onto a template to create an electrical connection between a number of carbon nanotubes.

These tubes were then "coaxed" into holes in order to create three-dimensional structures.

Researcher Srinivas Sridhar said that the technique has the potential to lead to large-scale manufacturing of single-wall carbon nanotube electrical applications.

Meanwhile, the University of Utah has unveiled its new Nano Institute, which will bring together scientists from a range of disciplines in order to study nanomaterials measuring as little as one-billionth of a metre.

Experts from several fields - including biology, chemistry, physics, medicine, engineering and pharmacy - will work at the site with the aim of taking nanoscience in Utah "from the scientist's bench to commercialisation", said co-director Marc Porter.
