Staph Detectors (IMAGE) University of Iowa Caption University of Iowa researchers have created a noninvasive probe that can detect a common strain of staph bacteria in the body. The staph bacteria are located via a light-emitting molecule (green), which is released when a bacterial enzyme (in orange) slices and separates the probe (shown in blue), shown in the illustration above.
