Novel paper biosensors can detect food contamination

Consumers are one step closer to benefiting from packaging that could give simple text warnings when food is contaminated with deadly pathogens like E. coli and Salmonella, and patients could soon receive real-time diagnoses of infections such as C. difficile right in their doctors’ offices.
Researchers at in Canada have developed a new way to print paper biosensors. The new platform enables users to generate a clear, simple answer in the form of letters and symbols that appear on the test paper to indicate the presence of infection or contamination in people, food or the environment. An article about the research is published in Chemistry (News Article McMaster University, 7 April 2015).
