Researchers at Georgia Institute of Technology have painted the smallest-ever image of Mona Lisa.
The painting was created using an atomic force microscope and a process called 'Thermo Chemical Nano Lithography' and is painted on a substrate that is 30 microns in width or about one-third the width of a human hair.
The painting by Keith Carroll from Georgia Tech proves that it is possible to create nanoscale devices using the latest technique as it could control concentration of molecules on small-scale.
