Scientists create smallest Christmas card ever

Nanotechnologists at the University of Glasgow have produced what they believe to be the world's smallest Christmas card.

The card has an image of a Christmas tree etched on a tiny piece of glass and measures 200x290 micro-metres.

Invisible to the naked eye, the card is so small that 8,276 of them could fit on an area the size of a postage stamp.

The point behind the creation of the card was to show how accurate nanotechnology is, according to the university's school of engineering.
