What chemicals can be detected with Ocean Optics SERS substrates, and at what concentrations?

We have tested a wide variety of analytes with our SERS substrates using a QE Pro-Raman spectrometer and 785 nm probe, as shown in the table below. The lowest concentration measured is also shown, but will vary with the sensitivity of the Raman instrument used for measurement.
