Another novel way of using gold in the world of science has come about in the form of a new memory device which may one day replace contemporary plastic systems.

Silicon-based memory apparatus such as those used in flash drives, computers and other applications may be phased out due to the invention of memory devices which use gold nanotechnology and an organic compound called pentacene.

Together these two materials provide great potential for memory because the gold nanoparticles are able to act as a charge-store facility enabling system sot store data. The gold is packaged within a citric acid.

Wei Lin Leong, from Nanyang Technological University in Singapore which is working on the breakthrough, said: "This approach of using citrate-stabilised gold nanoparticles as charge nanotrapsmay help lead to memory devices and circuits that can be integrated into low-cost, plastic electronics applications."

He said that the gold nanoparticles work in the mechanism by virtue of its simplicity in design and processing.

The researchers now hope to develop this invention into larger-scale work to make similar circuits for computer and television displays with more data storage memory.
