New paper test helps detect Salmonella

A new paper-based test could prevent people falling ill from foodborne pathogens, and improve food testing, according to research published in the journal Analytical Chemistry. Current testing for pathogens in food requires complicated machinery and trained personnel. But these tests don’t provide the simple results needed in large-scale food manufacturing. So Je-Kyun Park and colleagues set out to find a more practical way to detect foodborne pathogens. The researchers developed a paper-based test that can handle the multistep reactions necessary for this kind of analysis by controlling the pore size of the paper.  Read More
