FTIR and Raman Spectroscopy Applied to Dementia Diagnosis Through Analysis of Biological Fluids
Abstract
To date, it is still difficult to perform an early and accurate diagnosis of dementia, therefore significant research has focused on finding new dementia biomarkers that can aid in this respect. There is an urgent need for non-invasive, rapid, and relatively inexpensive procedures for early diagnostics. Studies have demonstrated that of spectroscopic techniques, such as Fourier Transform Infrared Spectroscopy (FTIR) and Raman Spectroscopy could be a useful and accurate procedure to diagnose dementia. Given that several biochemical mechanisms related to neurodegeneration and dementia can lead to changes in plasma components and others peripheral body fluids; blood-based samples coupled to spectroscopic analyses can be used as a simple and less invasive approach.
Keywords: Alzheimer’s disease; Fourier Transform Infrared Spectroscopy; Raman Spectroscopy; blood-based biomarkers; dementia diagnosis; disease fingerprint; metabolomic approach; vibrational spectroscopy.
