New technology has been developed by Hebrew University using gold to help boost the emerging nanotechnology sector.<BR/><BR/>The gold-tipped nanocrystals, can be used as highly efficient building blocks for devices in the sector.<BR/><BR/>Researchers at the university developed the nanodumbells, which are shaped like the mini-weightlifting bars and stop the need to build new nanocrystals transistors, the basic component of computer chips.<BR/><BR/>The nanocrystals have unique optical and electrical properties controlled by their size, shape and composition.<BR/><BR/>Gold tips were attached with a simple chemical reaction to a semiconductor to create the crystals and the strong chemical bond with the semiconductor creates a good electrical connectivity.<BR/><BR/>In addition the chemical bonding of the precious metal helps to solve problems involved in simultaneously producing billions of circuits.<img src="http://directnews.dehavilland.co.uk/dn.gif?feedid=196&itemid=2879653"/>
