Rochester Scientists Develop Fast-Working Biosensor

University of Rochester Medical Center scientists have demonstrated a new technology that accurately and rapidly detects the meat-spoiling and sometimes dangerous E. coli bacteria. The Rochester research team calls the technology "arrayed imaging reflectometry." The unique technology uses a protein from the suspect bacteria as part of the sensing system. The system also utilizes a silicon chip that is made so that laser light reflected off the chip is invisible unless the target bacteria are present. The technology potentially could detect any biological entity, Miller said. A physician someday, for example, could use the technology in his office to confirm a streptococcal infection in a patient with a sore throat.
