The news story made a big splash: in January 2016 ETH researchers Professor Raffaele Mezzenga and his senior researcher Sreenath Bolisetty published a study in the journal Nature Nanotechnology about an innovative type of membrane developed in their laboratory.
They showed that this membrane could effectively filter out heavy metals, radioactive waste, other toxic substances, and bacteria from polluted water. The filter can also trap ions of gold, platinum and palladium, allowing the recovery of precious metals. What's more, the composition of the membrane is extremely simple: a mixture of denatured whey proteins and activated charcoal applied to a filter paper as a substrate.
