A wide range of analytes can be detected in ultra-low quantities with our SERS substrates. Some use-case examples include:

Food Adulterants

Our SERS substrates have been shown to detect melamine in liquid infant formula reproducibily at 1ppm with minimal sample preparation.


With no sample preparation, thiram can be detected in apple juice with our substrate at 1ppm.

Pharmaceutical & Illicit Drugs

At a limit of detection of 100 ppb, we have shown that we can reliably identify cocaine in saliva using our substrate.
