dc.description.abstractThis thesis will explore the contribution of nanoparticles in enhancing Raman spectrometry, focusing on advances made so far in sensitivity, resolution, and applicability in a wide range of field applications. As a powerful optical technique, Raman spectrometry depends on the inelastic scattering of light to identify vibrational modes of molecules. However, it exhibits rather low sensitivity due to the weak Raman signal by nature. Introducing nanoparticles, especially through surface-enhanced Raman spectroscopy, increases the Raman signal enormously and permits the detection of trace molecules at a high level of detail. Among the various types of nanoparticles discussed here is the focus on gold and silver for their unique optical properties that enhance the electromagnetic field at the nanoscale level. This thesis will conduct experimental and theoretical investigations to see how nanoparticle morphology, size, and material composition affect Raman enhancement. The results show that optimizing the parameters of the nanoparticles leads to an improvement in the analytical capability and opens the way to new sensing technologies with high sensitivity and specificity.
