Gold is being used to help create nanoscale dumbbells, chains and tetrapods in new work by researchers in Israel.

Based at Hebrew University in Israel, studies have found a way to use tiny amounts of gold as tips on semiconductor nanocrystals that could end up being used as ultra-small transistors or memory elements in nanoelectronic circuits.

According to TRN, these developments are a key step towards solving the problems of how to wire such small objects together.

In addition, the nanorod-gold objects might also result in materials with new chemical and optical properties.

It is hoped the gold-tipped structures could be used in novel self-assembly within five years, whilst practical use in nanoelectronics is set to occur in the next five to ten years.
