Microscopic wires which could help form the miniature technology of the future have been constructed using the basic building blocks of living things.

The human body is one of the ultimate examples of a self-assembly machine, with every part a complex arrangement of intricately-folded proteins.

Experts in nanotechnology, who are trying to come up with ways of wiring the next generation of microscopic electronic circuits, believe that protein folding could hold the key to progress.

These could be “coated” in gold or silver, potentially producing wires thousands of times smaller in diameter than the tiniest available currently.
