“…5 More recently, IR resolution enhancement for carbohydrates was achieved by deconvolution methods, enabling the separation of a larger number of spectral bands for mono-, di-, and polysaccharides. 6 Most noteworthy from an analytical perspective, however, is the observance of vibrational spectral "fingerprints" for individual monosaccharides. A far-infrared study (500-100-cm -1 range) along these lines showed that each saccharide exhibited a characteristic spectral pattern, and development of an "encoding" method based on a sequence of relative intensities enabled the discrimination of different saccharides.…”

The sensitive detection and characterization of carbohydrates by means of a strategy based on surface-enhanced Raman spectroscopy is demonstrated. Spectra are obtained after injecting a small amount of saccharide solution onto a roughened silver substrate, with subsequent deposition of silver colloid. The sensitivity achieved by this two-step approach enables high-quality Raman spectra to be obtained for small amounts of aqueous saccharides (5 microL of a 10(-2) M solution) utilizing minimal laser power and small signal acquisition times (a few seconds). Spectral "fingerprints" obtained for seven structurally similar monosaccharides demonstrate clearly an effective means by which each sugar can be identified. The application to more complex analyses is demonstrated for monosaccharide mixtures and a disaccharide, whereby the SERS fingerprints aid in the determination of components.

“…The research on the spectroscopy and conformations of polysaccharides and model systems was subsequently continued [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The IR Fourier and Raman spectra of the basic types of mono-, di-, and polysaccharides and their derivatives were analyzed in detail (together with Polish colleagues from the Institute of Low Temperatures and Structural Studies, Polish Academy of Sciences, Wroclaw).…”

The versatility and originality of Z. A. Rogovins scientific creativity, his temperament, and work capacity significantly affected the evolution of research on the spectroscopy and conformations of polysaccharides, cellulose, in particular, new types of technically valuable derivatives, and on the whole, such a broad class of organic compounds as the carbohydrates.It is important to have a large number of derivatives with additionally incorporated different functional groups for developing research on the spectroscopy of the concrete classes of organic substances. This will allow solving the analytically important problem of setting up a data bank of the characteristic frequencies and intensities to a significant degree. In this respect, collaboration with Z. A. Rogovin and the analysis of the new types and industrially valuable derivatives of cellulose and other polysaccharides obtained under his direction in the Department and in the Problem Laboratory of Chemical Fibres opened up truly unique possibilities. The fact that all of these compounds were obtained for the first time was also especially important. The analysis of their structure and properties and the features of the appearance of the incorporated functional groups in the IR spectra of polysaccharides was pioneering. Since the newly synthesized objects, intermediate products of their synthesis, and model compounds had to be investigated in different aggregate states fibres, films, powders, this made it necessary to develop the optimum methodological conditions of nondestructive spectroscopic analyses.In a comparatively short time, we obtained and interpreted a large number of IR spectra of new types of industrially valuable cellulose derivatives containing chlorine, fluorine, sulfur, and phosphorus atoms, oxime, sulfhydryl, thiocyanate, and other groups, graft copolymers of cellulose with poly-2-methyl-5-vinylpyridine, carbochain polymers, complexing graft copolymers of cellulose with polyacrylohydroxamic acid, etc.The studies of the IR spectra of these compounds were extensively treated in our first monograph Infrared Spectra of Cellulose and Its Derivatives (1964). An updated and expanded version was published in English in New York in 1966 [1, 2]. The spectra of fibrous cellulose materials were obtained for the first time without using immersion media, with the method of direct modeling of fibres obtained abroad, called the Russian method. An extensive table of the characteristic frequencies of the different groups and bonds in the molecules of cellulose and its derivatives and the first atlas of the types of cellulose, products of its physical and chemical modification, the most important types of mono-, di-, and polysaccharides, and polyhydric alcohols is given in the book.The use of IR spectroscopy in this stage led to important conclusions; incorporation of bulky substituents, ester groups in particular, in the structure of cellulose does not lead to the appearance of hydroxyl groups free of hydrogen bonds, as was believed at the time; natural ...

The aldohexose glucose is the most abundant monosaccharide in physiological samples because of its metabolic importance for eucaryotic cells. d ‐Glucose exists in two stereoisomer forms, that is, the α ‐ and β ‐anomers, which also show differences in their vibrational spectra. The mid‐ and near‐infrared spectra and the Raman spectra are presented in comparison mainly to the hexose of fructose (a furanose). Spectral data are illustrated for the crystalline substance and for glucose in aqueous solutions. The latter spectra are important for analytical applications within the life science area for reagent‐free spectroscopic assays, competing with conventional enzyme‐based amperometric biosensor technologies. For quantitative biofluid analysis, multivariate calibrations are usually employed to achieve the required assay selectivity. Besides biotechnological applications clinical methods are also described, which aim at the analysis of whole blood and derived fluids, and of others such as urine or the aqueous humour of the eye. In addition, activities with regard to noninvasive blood glucose measurements are described.
