Scan Your Food With Your Cell
By Dane Carlson on February 29, 2012 in Inventions
Have you ever been tempted to order steak tartare but decided against it for fear of getting sick? This little cell phone scanner can take a look at it for you and let you know if it does in fact harbor any E. coli bacteria.
It attaches to a typical cell phone camera and uses fluorescence imaging to detect the bacteria. Engineers at UCLA combined quantum dots, a type of tiny semiconductor, with capillaries containing antibodies. When the capillaries contain an E. coli sample, they emit light.
