High School Students Invented a Device for Water Pollution

A high school junior who has already invented a pancreatic cancer sensor and a handheld explosives and environmental contaminants detection device developed a new sensor that deals with water pollution.

Kid genius Jack Andraka along with classmate Chloe Diggs created a life-saving microfluidic biosensor that can quickly and cheaply detect water contaminants. The credit card-sized biosensor acts as a water filter that can detect six environmental contaminants. It only takes $1 to create and takes 20 minutes to run, rendering it significantly cheaper and more efficient than comparable water pollution-fighting sensors. Part of the project also included a water filter composed of recycled water bottles.

The Siemens We Can Change the World Challenge first place national winner for grades 9 to 12 recently took home a $50,000 prize.
