Extra virgin (EV) olive oil has been characterized by means of micro-Raman spectroscopy. In order to overcome the natural fluorescence of oil a seed layer of Au nanoparticles (GNP) has been used on the top of microscope glass substrates that hosts the liquid sample during the measurement. This method enhances the Raman signal with respect to fluorescence and allows to obtain a deep insight on the chemical and structural state of the sample.

Abstract
Extra virgin (EV) olive oil has been characterized by means of micro-Raman spectroscopy. In order to overcome the natural fluorescence of oil a seed layer of Au nanoparticles (GNP) has been used on the top of microscope glass substrates that hosts the liquid sample during the measurement. This method enhances the Raman signal with respect to fluorescence and allows to obtain a deep insight on the chemical and structural state of the sample.File in questo prodotto:
