• Resumen

  • A handheld sensor, developed by Raj Mutharasan at Drexel University in Philadelphia, that can quickly spot contamination by deadly strains of the Escherichia coli bug could help prevent infected food reaching consumers. In the US alone, 60 people a year die from E. coli, while 73,000 are infected with pathogenic strains. But detecting the bug is a slow process that involves removing whole batches of foodstuffs from production lines while cultures are grown or DNA amplified. Details of the device that a offers a 10-minute test are presented.
