Current methods for detecting water-borne pathogens require a laboratory setting, analyte preparation and typically a day or more. The author, a solid state device physicist, has invented a methodology capable of the real-time (1 - 2 second) detection of water-borne pathogens without analyte preparation and without human intervention. The patent protected methodology combines a novel design of field effect transistor together with the developing science of molecular probes to create a sensor of extremely high sensitivity (single cell). Transistors can be sized for various pathogens from protozoa to bacteria to viruses, and then functionalized for targeted pathogens. The sensor is self-regenerating: After a short period of time, a transistor is again available for detection of a targeted pathogen. Bisen’s sensor and methodology is suitable for hand-held portable devices to large fixed installations. Every 8 seconds someone in the world, most likely a child, dies from a water-borne illness. One in six americans experience food poisoning each year. Bisen’s sensor is the only sensor capable of acting as a sentinel to prevent contaminated water and food from ever reaching consumers.
