Extraction and Detection of Human Pathogens using Antibody Modified Electrospun Conducting Polymer Fibers

Warriner, Keith
University of Guelph
Start date
End date
  1. Optimize fabrication of conducting polymer composite electrospun fibers.
  2. Immobilization of aptamers or antibodies onto electrospun fibers.
  3. Evaluate the capture efficiency of model pathogens (Salmonella, E. coli O157:H7 and Listeria monocytogenes) of optimized fibers.
  4. Detection of captured pathogens using electrochemical or optical transduction.
  5. Verification of sensor performance in model food matrices.

Expected Benefits: By providing a low cost sensor, it will be possible for processors to increase testing within facilities thereby reducing the risk of future listeriosis and other foodborne illness outbreaks.
