        This short report presents an idea about the work of my master's degree, which was done at the chemical laboratory of the national research center under the direction of Mr. Pietro Giuseppe Gucciardi and which had presented at the Faculty of Sciences of Sfax under the supervision of Mr. Ramzi Maalej and Mr. Walid Rekik. The goal of this subject is the study of the demethylation of Methylene blue induced by Plasmon excited in different types of nanoparticles as gold and silver. In this update, we have done a literature review on nanoparticles that have received a fast-growing increased interest in recent years due to their unique physical and chemical properties, which are expected to open new novel avenues of different technological, environmental, and biological applications of these nanomaterials in catalysts, semiconductors, sensors, drug carriers, and personal care products. Subsequently, using the different experimental techniques (Raman spectrometer, SERS, labspec), we observed the demethylation phenomena in different samples at different powers of the laser, starting with the dried drop of methylene blue as a reference. Finally, by analyzing the data and comparing the dried drop of methylene blue with the metal nanoparticles, we concluded that gold PLD is more efficient than other samples, in which photo-degradation occurs more rapidly.
