Biofilm-Based Sensor Systems

The Center for Innovation, in collaboration with the Center for Biofilm Engineering at Montana State University and Research International, Inc. has developed a prototype device for sensing pathogens in drinking water distribution systems.  Many traditional sensor technologies are hindered during continuous use due to biofouling of the sensor.

 

The CFI system incorporates the natural phenomenon of biofilm formation into the design of the sensor system.  Biofilms formed by natural drinking water microorganisms serve to capture and concentrate passing pathogens, thereby improving detection capability.  The prototype device is capable of continuous on-line monitoring of drinking water for pathogens including bacterial cells, bacterial spores, and protozoan oocysts.
