Clean drinking water is a shrinking resource that the whole world is now becoming aware of . The top priority now is to find a way to take the polluted water around us and making it potable in the easiest and most cost effective manner. It is this need that made Theresa Dankovich turn to nano technology even as she studied the material properties of paper.

Based on her initial research work scientists has now come up with a new filtration device which is being termed the “drinkable super book”. The pages of this book have been embedded with bacteria killing metal nano particles. The simple, inexpensive method uses pages from this book which are slid into a special holding device in to which the water is poured for filtration.

This water is then filtered through the book’s special page, killing the bacteria through nano technology and being collected in the holding device below. A single page infused with this nano technology can filter nearly a hundred litres of water. That is equal to a single person’s water requirement for nearly four years. Needless to say this science project has the potential to bring safe drinking water to a number of inaccessible regions worldwide.
