Rapid diagnostic test for pathogens, contaminants

Using nanoscale materials, researchers have developed a single-step method to rapidly and accurately detect viruses, bacteria and chemical contaminants. The scientists were able to detect compounds such as lactic acid and albumin in highly diluted samples and in mixtures that included dyes and other chemicals. Their results suggest the same system could be used to detect pathogens and contaminants in biological mixtures such as food, blood, saliva and urine.
