New biosensor rapidly detects deadly foodborne pathogen
...ith compromised immune systems are most at risk of contracting
the disease. The bacteria classified as Listeria include six different species, but only L. monocytogenes can infect humans. This makes it especially important to develop highly selective sensors that can detect only L. monocytogenes, Bhunia sa...
