Mini Lisa
The ''Mini Lisa'' is a nanoscale replica of the ''Mona Lisa''. It was created in 2013 by Keith Carroll, a Georgia Institute of Technology PhD candidate, in order to demonstrate a technique called thermochemical nanolithography (TCNL) that was invented at the university. In TCNL, a tiny cantilever viewed through an atomic force microscope uses heat to activate a series of chemical reactions that create new molecules. Greater amounts of heat create more molecules which lighten the surface of the substrate, allowing a gray-scale image to be created.
The ''Mini Lisa'' is just wide, about a third the width of a human hair.〔 It is roughly 1/25,000th the size of the ''Mona Lisa''. The ''Mini Lisa'' was created by making hundreds of individual points each wide.〔 Carroll decided to recreate the ''Mona Lisa'' after a challenger claimed TCNL was not precise enough to create a work of art. He created an automated process to create any image desired based on a supplied heat map.
The ''Mini Lisa'' project, which also included recreations of photographs by Ansel Adams, was published in ''Langmuir'' in August 2013.〔 The paper's lead author, physicist Jennifer Curtis, said the experiment demonstrated for the first time that it was possible not only to manipulate molecules on a nano-scale, but also precisely control how many are there. She said that TCNL "should enable a wide range of previously inaccessible experiments" in a diverse set of fields as it evolves.〔〔 The project also received mention in the popular press.〔
