Nanotech create world’s smallest Christmas card

Nantotechnologists at the University of Glasgow have created what they believe is the world’s smallest Christmas card.

The card is so small it could fit on to the surface of a postage stamp 8,276 times.

The image, which measures 200×290 micro-metres, features a Christmas tree and is etched on a tiny piece of glass.

The team behind the project said the technology could eventually be used in products such as TVs and cameras.

The university’s school of engineering drew up the design to highlight its “world-leading” nanotechnology expertise.
