The test, which uses fluorescent nanocrystals, was developed to diagnose pregnancy but could also be used to detect drugs, pathogens and allergens. The test offers several advantages over current methods, including the ability to test several substances on one strip because of the many colors of quantum dots excited by the same wavelength, the release said.
