 both cases, the intensity of key Raman peaks scaled via a well-defined relationship with concentration, even down to very low concentrations.
When considered in combination with the field-ready performance of the IDRaman mini and the sensitivity of Ocean Optics SERS substrates at a low cost-per-use, these results indicate a very promising future for use in both the legal system and hospitals.
