Artistic rendering of water sensor with graphene-based nanolayer and two electrodes attached at top. Alternating current voltages at varying frequencies (wavvy lines) are used to rapidly and non-destructively screen for high-quality sensor devices.
Newswise — In a world grappling with a severe water crisis, contamination is a looming threat to public health. Researchers at the U.S. Department of Energy’s Argonne National Laboratory and partners have engineered a breakthrough solution. Their new screening method could eliminate faulty electronic sensors for measuring numerous toxins in water, such as bacteria, heavy metals, pesticides and coronaviruses.
Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation’s first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America’s scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy’s Office of Science.
The U.S. Department of Energy’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time. For more information, visit https://energy.gov/science.
