World's smallest 'Mona Lisa' created using DNA origami
Caltech scientists have made the world's smallest recreation of Leonardo da Vinci's Mona Lisa, the size of bacterium, out of DNA. The technique, dubbed DNA origami, enabled scientists to fold DNA into desired self-assembling structures using 64 tiles, which were 100 nanometers wide. The team also created a life-sized portrait of a bacterium and a bacterium-sized portrait of a rooster.
