Description
Raman Spectroscopy was identified as a valuable tool in material identification, biology, and medicine. Raman Spectroscopy was used to identify molecular vibrational “fingerprints” and the evidence of protein samples. In this experiment Raman Spectroscopy was initially investigated as a method for detecting protein samples through their characteristic vibrational spectrum. However, because Raman scattering signals are often proven weak for this protein sample, conventional Raman spectroscopy did not produce sufficiently strong signals for the specific samples analyzed. To address this limitation, Surface-Enhanced Raman spectroscopy (SERS) was employed. SERS enhances Raman scattering by utilizing nanostructured metallic surfaces, which amplifies the Raman signal of molecules. This enhancement enables improved sensitivity for the detection and identification of protein samples. The results demonstrate that SERS provides a more effective approach for detecting proteins when traditional Raman scattering yields insufficient signal intensity.
