Detection of Food Pathogens
Purdue University researchers have developed a biochip that detects pathogens in foods in real time and a method for using and maintaining the device. Cells are first concentrated. Then, the device can be put in the cell recovery mode to collect the retentate. The researchers developed a novel method for collecting the retentate so that the microbes can be analyzed. Accompanying software controls the unit's operation and allows for simultaneous filtration and cell recovery. The researchers have also developed a method for cleaning and sterilizing the instrument to allow reuse and address membrane fouling, which is the build-up of lipids, proteins, and other particles that block the membrane so fluid cannot flow through. Both developments will reduce costs associated with pathogen detection by extending the life of the equipment.
