I know it’s a few days past Christmas but I couldn’t pas by this news.

Nanotechnologists at the University of Glasgow, Scotland, Produced what they believe to be the world’s smallest Christmas card, the image of a Christmas Tree engraved on a piece of glass, a very small piece of glass, invisible to the naked eye.

“The card is 200 micro-meters wide by 290 micro-meters tall. To put that into some sort of perspective, a micro-meter is a millionth of a meter; the width of a human hair is about 100 micro-meters,” explains David Cumming, professor at the University of Glasgow.

To make it easier for you to imagine its real dimensions I should tell you that on an area the size of a postage stamp you could fit around 8,276 of these cards. Color was also added using a process called plasmon resonance.

Scientists had the sole purpose of explaining what nano-technology is capable of and say that, while the card is just a demonstration, domains like the electronics industry find this technology very useful.
