New biosensor research by doctoral student Lateef Syed and
professor Jun Li of Kansas State University may be useful in detecting
pathogens that would improve food and water quality and reduce health risks. The
student-professor team is developing a biosensor that detects of E. coli for the
meat and poultry industry, but sees use for discovering other pathogens as
well.
To develop the biosensor, Syed and Li use carbon
nanofilters, which form tiny electrodes that are small than the bacteria they're
trying to capture. When the microbial particles are captured at the electrode
surface, the sensor detects an electric signal.
The team ultimately hopes to integrate their technology into
a hand-held, pathogen-detection device that can monitor the quality of food and
water quality at industrial processing locations. The project is being
supported by Canadian-based Early Warning Inc. and the United States Department
of Homeland Security Center of Excellence for Emerging and Zoonotic Animal
Diseases.
