초록
The potential application of surface-enhanced Raman spectroscopy (SERS) was investigated todetect Salmonella Typhimurium and Escherichia coli. The silver colloidal suspension withoptimum optical characteristics was obtained for SERS detection. The SERS spectra werecollected the wavelengths from 500 to 1200 cm-1. The characteristic SERS spectra were obtainedfrom both S. Typhimurium and E. coli; however the observed SERS peak profiles for bothpathogens exhibited similar peak profiles. Therefore, the results suggest that even though SERSpossesses the potential capability to detect pathogens rapidly, further study is required to resolvethe ambiguous spectra profiles for S. Typhimurium and E. coli.
