The Mona Lisa painted the width of a hair

By Casey Frye, CCNN Writer

My teacher told me he was surprised when he saw the Mona Lisa, one of the world’s most famous pieces of art. At only a few feet tall and a few feet wide, it was so much smaller than he expected! Well, this new painting from the Georgia Institute of Technology will blow his little cotton socks off. You see, its width is less than half a hair thick! The university was trying to demonstrate the accuracy of a new technique they call ThermoChemical NanoLithography, which uses heat, chemicals, and microscopes to design really small creations. Just to show how accurate they could be, they made a miniature picture of Leonardo Da Vinci’s most famous painting and called it the “Mini Lisa.” Sure it’s a little fuzzy-looking, but considering it’s no thicker than a hair, it looks great! They hope the technique will eventually be used to make  tiny devices that can be a bit more useful than the tiny Mona.
