Researchers have used gold particles and polystyrene to create a thin film for information storage.<br/><br/>The Rohm and Hass Electronic Materials Company and researchers at the University of California at Los Angeles have devised the material, which is low cost and offers high speed non-volatile memory.<br/><br/>According to TRN Magazine, the researchers claim the memory is potentially much faster than today's CDs and DVDs in terms of reading and information being written onto it.<br/><br/>A layer of polystyrene and gold particles is sandwiched between aluminium electrodes and is easy to make, using little power.<br/><br/>In addition, layers of the film can be stacked, allowing it to store even more information.<br/><br/>When testing the material, the researchers prepared a solution of polystyrene and gold nanoparticles ranging from 1.6 to 4.4 nanometers in diameter and used spin casting to produce the thin layer.<br/><br/>It is hoped the device could be used practically within two to five years.<img alt="track" src="http://directnews.dehavilland.co.uk/dn.gif?feedid=196&itemid=8098606"/>
