The raman spectra
Webb29 mars 2024 · The study found that Raman spectroscopy could accurately distinguish between healthy blood samples and blood samples from patients with thyroid disorders. The study also found that machine learning algorithms could be used to predict the presence of thyroid disorders based on Raman spectroscopic data. WebbRaman spectrometry is a powerful tool for analyzing and monitoring the chemical composition of materials. Each compound has its own unique Raman spectrum. Therefore, it is necessary to have a library of Raman spectra for successful use of the method.
