The Surface
Enhanced Raman Scattering (SERS) Probe program is developing
a portable, high-sensitivity probe for the detection of contaminants in water, with a
focus on environmental waters, agricultural waters, and food process waters.
The probe
utilizes Raman Spectroscopy for the detection of contaminants, in which an
intense laser light source illuminates a sample, and a signature spectrum can
be recorded, to be compared against spectral libraries to provide a chemical
identification. SERS exploits an effect whereby chemicals in close
proximity to a roughened metal surface (usually gold or silver) have a greatly
increased Raman response. The
significantly increased sensitivity of the SERS technique opens an opportunity
for the development of new portable instrumentation for water analysis.
