Vibrational Biospectroscopy in the Clinical Setting: Exploring the Impact of New Advances in the Field of Immunology

Figure 1

Generating unique FTIR spectra for biological samples. Following interaction with IR light, the changes in light absorbance can be measured and a biological spectral fingerprint generated. The characteristic spectrum of blood serum (red) and plasma (blue) are illustrated, with six key wavenumber peaks highlighted alongside their associated biomolecular component assignments.
