The team claims that the test is easier to use than a Covid-19 home test.
causes around 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the U.S each year. This foodborne disease has a strong resistance factor and fast reproduction rate. Foodborne illnesses such as Salmonella costs the U.S over $15.6 billion each year.are time consuming, labor intensive and cost a lot of money.have developed a faster and better test method to check for Salmonella contamination in food products like chicken.
The first is a new synthetic nucleic acid molecule that interacts with Salmonella, which was developed in-house by the team. This molecule is sandwiched between layers of gold microscopic particles. The composite material lines the inside of the tip of a glass pipette. When a liquified sample of a food is drawn inside the tube, that interaction leads to an action.
Here we come to our second component. If salmonella is present, the bacteria will cut through the gold microparticles allowing nucleic acid to escape into the liquid sample. When this solution is dropped onto a piece of paper, the droplet will change color to red to mark the presence of salmonella. The greater the concentration of the bacteria, the brighter the shade of red.The test can be performed without a power source and takes about an hour to yield accurate results.
