Researchers have created the lightest ever gold foam, which could lead to new applications in jewelry, pressure sensors and experiments.
Developed by a team from ETH Zurich, the gold foam is made up of 98 percent air and only 2 percent solid material. To make the foam, the team suspended amyloid fibrils in water and then mixed them with salt and differently sized gold particles. Carbon dioxide was then used to dry the gel (protecting the protein structure), resulting in a 20 carat gold material light enough to float on a layer of milk foam.
