How to Make Molecular Devices? Microscopic DNA Tools May Be Key

DNA codes for life as we know it, but in recent years, scientists have discovered more uses for the molecule. Because DNA is foldable and “sticky,” they’ve begun making microscopic shapes called DNA origami. Over the last decade or so, researchers have improved at this DNA art, and now, Caltech scientists say they used DNA to sketch a glowing masterpiece — a replica of Vincent van Gogh’s famous painting “The Starry Night”— on a canvas the size… read more
