About This Webinar
Raman spectroscopy is a powerful analytical technique that enables the quick and non-destructive identification of chemical signatures of a sample analyte. With the added capability of integrating with nanotechnology for enhanced performance, such as surface-enhanced Raman spectroscopy (SERS), this technique has been extensively applied in food analysis for the detection of food components, additives, and contaminants.

He discusses the use of Raman spectroscopy for differentiating antioxidant isomers, quantifying mixture components, characterizing chemical responses to thermal processing, and measuring the chemical distribution in encapsulation.

Additionally, two innovative SERS substrates introduced, the nanoparticle mirror and the SERS needle. The nanoparticle mirror substrate can be utilized as a coating for surface pesticide analysis, while the SERS needle offers the ability for volatile spoilage marker detection in package headspace, multiphase detection, and minimally invasive analysis.
