The pages from this ¡¦Drinkable Book¡¦ can purify contaminated drinking water for an entire year
¡@¡@780 million people around the world lack access to clean drinking water and 3.4 million people die every year from diseases related to contaminated water. Theresa Dankovich¡A a chemist who did her PhD at McGill University and is now a postdoctoral fellow at the University of Virginia¡A is hoping her new invention can help.

¡@¡@Dankovich has designed a simple paper that¡¦s coated with disease-killing silver nanoparticles that works like a technologically advanced coffee filter. Pour contaminated water through the paper and it kills 99.99 percent of the bacteria¡A which results in drinking water that¡¦s as clean as US tap water.

¡@¡@Dankovich has partnered with WATERisLIFE¡A an international non-profit¡A to get the filter papers into the hands of people who need them. They¡¦ve come up with an ingenious idea: the Drinkable Book¡A which provides enough filter paper for a year¡¦s worth of clean drinking water.

¡@¡@Stacks of Danvovich¡¦s paper are bound into a single volume and placed in a 3-D printed box that doubles as a filter container. The whole thing couldn¡¦t be easier. Tear a sheet out of the book¡A slide it into the container¡A pour contaminated water¡A and presto: you¡¦ve got clean drinking water in the amount of time it takes to fill up a Brita.
