Surface Enhanced Raman Scattering (SERS) is an anomalous enhancement of Raman scattering when molecules are adsorbed to gold or silver nanostructures – this enhancement can be as large as 10¹¹. The advantage of SERS over traditional Raman spectroscopy is its ability to detect analyte concentrations of parts per million, and even parts per billion levels, while Raman spectroscopy works best for pure samples and some simple mixtures.
Potential application areas include:
Metrohm's SERS materials offer key benefits:
Potential application areas include:
P-SERS test strips have nanoparticles printed onto cellulosic substrates using inkjet technology. This method produces inexpensive test strips that exhibit exceptional stability and sensitivity.
Poly-dispersed 50 – 200 nm diameter nanoparticles are stabilized in an aqueous solution. Each batch is fully tested and validated for SERS performance as part of the production process.
SERS Discovery Kit is an introductory kit for SERS containing a complete selection of Metrohm’s gold and silver P-SERS strips and gold and silver colloids. This kit can be used to evaluate the suitability of SERS for targeted applications.
