‘Drinkable book’ filters filthy water and makes it safer to drink, researchers say

Imagine a book that has pages you can tear out and use to turn raw sewage into drinking water. Each page is implanted with silver or copper nanoparticles that kill bacteria when water passes through them. And each page is printed with a message in your local language: “The water in your village may contain deadly diseases. But each page of this book is a paper water filter that will make it safe to drink.”
