Development of a highly sensitive enhanced Raman spectrosensor for the identification of foodborne pathogens

Investigator: Joseph Irudayaraj (Department of Agricultural and Biological Engineering)

Project Report 2011 - 2012

Project Description:

Surface enhanced Raman spectroscopy (SERS) can be used to detect bacteria in a food system by identifying different spectra that are unique to each bacterium, much like fingerprint analysis. The SERS signal enhancement enables the detection of low concentrations of pathogenic bacteria in food samples.

Project Highlight Quote:

Raman spectroscopy-based biosensors can detect foodborne pathogens and the portable system being developed will enable on-site detection.
