20 Medical Applications of NIR Spectroscopy

Fig. 20.4 Diffuse reflection spectra of crystalline sugars and two polysaccharides with glucose as
structural subunits
Fig. 20.5 Absorptivities of glucose and fructose obtained from measurements of aqueous solutions and of glassy monosaccharides from syrup after water evaporation (scaled to aqueous phase
absorptivities)
for further clinical applications. Such quantitative data for glucose, alanine, ascorbate, lactate, triacetin and urea have been used for evaluating the selectivity of NIR
spectroscopic clinical assays, using the combination band (5000–4000 cm
−1 ) and
first overtone region (6450–5400 cm
−1 ) or for the development of non-invasive blood
