WARF: P190123US02
Inventors: Sundaram Gunasekaran, Batul Unchwaniwala, Anu Prathap Mylamparambil Udayan
The Wisconsin Alumni Research Foundation is seeking commercial partners interested in developing a low-cost and user-friendly arsenic detection method. Easily synthesized nanoparticles are combined with robust electrochemical detection, resulting in a limit of quantification for Arsenic (III) of 0.075 ppb, well below the guideline values of the United States Environmental Protection Agency (EPA) and World Health Organization (WHO).
The Invention
UW-Madison researchers have developed an easy, cost-effective and eco-friendly synthesis for gold nanoparticles that can be employed for electrochemical detection of toxic Arsenic (III) and Arsenic (V) in water. The method enables cost-effective detection without sophisticated laboratory equipment and improves upon prior electrochemical methods that are expensive, time-consuming and subject to interference from common metals in drinking water. The method has been successfully applied to measure Arsenic (III) in authentic tap water samples with excellent quantitative performance and a limit of quantification well below the EPA and WHO guidelines.
