Caption: There are good E. coli and bad E. coli. Some live in your gut and help you keep healthy, others can cause serious disease -- even death. For pathologists, telling them apart has been a long and laborious task sometimes taking days. New technology, developed in the lab of Mark Hayes at Arizona State University, using microscale electric field gradients now can tell the difference between good and bad bacteria in minutes from extremely small samples. Shown are generic E. coli and bacteria populations isolated on a microdevice.
