Scientists created a mini-Mona Lisa that is only 30 microns across, 1/3 the width of a human hair! Using the Mona Lisa as the image to do this isn't much of a surprise, she is probably the most re-created work of art in the world - and in space.

She was also used as the test image to test a new technology to send a picture to the moon. What's even more ironic is that the actual Mona Lisa is made up of layers of paint that are almost as tiny as this nanotechnology - each layer being microns thin. Why people use the painting as the go to image to test new technologies is obvious - but what is not so apparent is why (and how) Leonardo da Vinci used these similar techniques over 500 years ago?

"Using a novel nanotechnique, researchers have made a miniature Mona Lisa that stretches 30 microns across, just a third of the width of a human hair.
A team from Georgia Tech created the molecular masterpiece using an atomic force microscope and a process dubbed ThermoChemical NanoLithography, or TCNL for short.
Each 125-nanometer pixel of the "Mini Lisa" represents a confined set of chemical reactions. The technique allowed the researchers to control the amount of heat applied over each pixel to vary the number of new molecules created in each spot. More heat resulted in more molecules and lighter shades of gray. In this way, the team made the tiny copy of Leonardo da Vinci's most famous work, pixel by pixel." Source
