Scientists at the Georgia Institute of Technology have recreated the world’s most famous painting – the Mona Lisa – on the world’s smallest canvas. The “painting,” on a substrate surface approximately 30 microns in width, is actually about a third the width of a human hair.
The image was produced using Agilent’s 5600LS atomic force microscope through a process called ThermoChemical NanoLithography (TCNL) that could eventually result in the nanomanufacturing of devices.
“We envision TCNL will be capable of patterning gradients of other physical or chemical properties, such as conductivity of graphene,” said Jennifer Curtis, an associate professor in the School of Physics and the study’s lead author. “This technique should enable a wide range of previously inaccessible experiments and applications in fields as diverse as nanoelectronics, optoelectronics and bioengineering.”
