Scientists at the thin-film laboratory of Vladivostok-based Far Eastern Federal University (FEFU) have mastered the art of making nano-portraits, the Russian media have reported.
According to Alexander Samarda, an associate professor of FEFU’s computer systems department, the nano-portraits are created on a 50-nanometer thick polymer film pre-applied to a silicon substrate.
“By using an electronic beam two nanometers in diameter, we can draw any shapes and figures with precision,” the scientist explained.
The FEFU lab has already created a few ‘nano-masterpieces,’ including nano-portraits of President Vladimir Putin of Russia, Prime Minister Dmitry Medvedev, and even a nanostructured copy of Leonardo da Vinci’s Mona Lisa (or La Gioconda).
“We can place about 40 nano-portraits of the Russian president on a section of a hair,” Mr. Samarda said.
