It can take as long as 24 hours to detect toxins in the body, meaning the people affected could be long gone by the time medical personnel figure it out. Thanks to the work of Crystal Diagnostics and its partners, that may all change. Crystal Diagnostics -- with its parent company Pathogen Systems Inc. of Colorado -- is developing liquid crystal biosensors to detect pathogens in real-time, instead of a day. The detection device -- invented jointly by researchers at Kent State University and the Northeastern Ohio Universities Colleges of Medicine and Pharmacy in Rootstown -- combines liquid crystal technology and antibody research. Crystal Diagnostic currently employs 15, and but the company expects to add a dozen more jobs when the device goes "live."
