Gold has been employed in the development of a new microchip that uses a unique nail structure to accurately record the electrical activity and communications of biological cells.

The device has been created by nanotechnology specialist Imec to provide a close contact point for single electrogenic cells within a network.

Electrogenic cells such as cardiomyocytes (heart cells) and neurons (brain cells) use electrical signals to communicate with each other. By monitoring and stimulating this communication, Imec hopes to explore issues such as the development of emotions and memories, the ability of neurons to form new connections and the possible origins of degenerative diseases such as Parkinson's and Alzheimer's.

When cells are applied to the surface of the microchip, its metal nail structure, which is covered with an oxide lay and conductive material including gold, becomes embedded in the cell membrane, providing close contact that reduces interference and allows more precise reading of electrical activity.

Imec director of bio-nanoelectronics Kris Verstreken said in the long-term, the microchip could be used to diagnose diseases "or even develop therapies by stimulating cells or building new communication bridges between cells".

Established in 1984, Imec is headquartered in Belgium and has offices in the Netherlands, Taiwan, the US, China and Japan. The company employs around 1,650 people.
