E. coli, Sensor Developed 6/4/2007 Source of Article: http://www.freshplaza.com/news_detail.asp?id=2290 A Drexel University engineering professor has developed a millimeter-size cantilever biosensor that can detect cells and proteins in trace samples and in only minutes. The sensor could have wide applications in medical diagnostic testing (prostate cancer), detecting contamination in food products (E. coli bacteria) and monitoring for biothreat agents (anthrax). In medical testing, the sensor can be used to analyze the four most widely tested fluids: blood, urine, sputum and spinal fluid.
