How the gold is recovered: Gold ions adhere to a sponge of protein fibrils. Credit: Peydayesh M et al. Advanced Materials, 2024, adapted. When they placed the protein fiber sponge in the metal ion solution, the gold ions adhered to the protein fibers. Other metal ions can also adhere to the fibers, but gold ions do so much more efficiently.
