How do Misa and Surface-Enhanced Raman Scattering work?

Contamination of food is a global problem, whether it is done intentionally for profit or accidentally through negligence, the end result is the same – consumers pay the price.

The problem of food contaminations can be addressed with complex analytical laboratory techniques such as GC-MS and HPLC, but time, skill, and cost requirements limits their usage to the confines of well-equipped laboratories. Surface Enhanced Raman Scattering (SERS) – an extension of Raman spectroscopy - permits detection and identification of analytes in concentrations as low as parts per billion. Food analysis with SERS can be fast, convenient, and inexpensive.

SERS utilizes nanotechnology with Raman spectroscopy to enable trace detection of adsorbed molecules. When a sample is applied to Metrohm’s SERS material, the nanostructures generate millions of times enhancement to Raman scattering, and detection of trace-levels of analytes is readily achievable. SERS is an extremely attractive technique as it retains all of the appealing features of Raman – portable equipment, multi-analyte detection capabilities, and rapid analysis.

Misa from Metrohm is a dedicated instrument for performing SERS measurements. Misa was developed with the focus for a simple, efficient and green testing solution to address food safety threats. Easily swappable attachments allows flexibility of testing using different types of SERS materials. Metrohm also provides targeted ID Kits that include test materials as well as detailed step-by-step instructions for measurement of common contaminants in various food matrices.
