Not actual size.
A team at the Georgia Institute of Technology has "painted" the world's smallest replica of the Mona Lisa. It is 30 microns wide, which is one-third the width of a human hair! They used heat to manipulate molecules into different concentrations for the different shades.
They have called their nanoscale painting the "Mini Lisa".
"By tuning the temperature, our team manipulated chemical reactions to yield variations in the molecular concentrations on the nanoscale. The spatial confinement of these reactions provides the precision required to generate complex chemical images like the Mini Lisa," said Jennifer Curtis, an associate professor in the School of Physics and the lead author of the study.
