Scientists have developed '2D' gold so fine that even a human fingernail is thicker in comparison.

The scientists at the University of Leeds, have created the world's thinnest gold measuring two atoms thick or million times thinner than a fingernail.

In its 2D form, gold becomes flexible that adds to its potential of being used more efficiently such as in bendable screens, electronic inks, medical diagnostic tests, and water purification systems.
