The 'Mini Lisa' Brings the Mona Lisa to a Molecular Scale

The 'Mini Lisa' is an extremely miniature version of the famous Mona Lisa painting. The minuscule piece of art is so small that it only stretches to about a third of the width of the average human hair. Mini Lisa was created using ThermoChemical NanoLithography in order to make it only 30 microns long.

Researchers at the Georgia Institute of Technology created the micro-painting using chemical reactions to shade in pixels. Heat was used to create molecules at differing amounts across a substrate surface. The machine used to create the painting used more heat for lighter areas and less heat for darker areas. As a result, the researchers were able to create an accurate depiction of Mona Lisa at a molecular scale.

The Mini Lisa is only part of the journey towards widespread nanomanufacturing. The researchers hope to use their discoveries to further the field.
