With heightened concern about E-Coli, researchers may have a detection solution at hand.
Drexel University Chemical Engineers have developed a handheld device that can identify as few as four cells of a biohazard. The electronic meter will hold replaceable sensors, sort of like glucose test strips. Once the sensor touches a solid or liquid, the cantilever vibrates. The device reads the frequency of the vibration to determine whether E-Coli is present.
The device is expected to be available to the food industry sometime next year.
