In order to increase young people's interest in nanotechnology, scientists have managed to put a version of the Bible on a chip smaller than a pinhead.

The record for the smallest copy is held by a Bible measuring 2.8x3.4x1cm (1.1x1.3x0.4in), weighing 11.75g (0.4 ounces) and containing 1,514 pages.

The 0.5sq-mm (0.01sq-in) nano-Bible was written on a silicon surface covered with a thin layer of gold (20nanometres thick - 0.0002mm).
