Surface Enhanced Raman Spectroscopy: A Metrological Tool for Fungicide Detection

• Abstract:

  The scope of this work is to standardize a Surface Enhanced Raman Scattering methodology for the detection of food contaminants in order to provide good compromise between sensitivity and reproducibility of analysis. A stable methodology to analyse fungicide’s traces directly on fruit peal by depositing gold nanoparticles on its surface is proposed. Different types of AuNPs for SERS where synthetized and tested. A comparative study between different AuNPs was performed in order to maximize the enhancement factor. Sensitive and specific method for in-situ detection is provided and two different strategies for quantification are proposed. A standardized method based on SERS technology for the analysis of fungicide traces on an apple’s peal was set and validated.
