University of Arizona (UA) researchers have created a smartphone app that detects small amounts of norovirus (the most common cause of gastroenteritis) in water, when combined with a microscope attachment and a light source.
UA's Jeong-Yeol Yoon said the technique can identify as little as 10 attograms (10-17 grams) of norovirus per milliliter of water, outperforming other portable detectors by six orders of magnitude.
The researchers are using the app to monitor groundwater sources in Tucson, AZ; it allows them to test water sources directly, rather than needing to bring water samples to a lab.
