Reflection-absorption infrared spectroscopy of self-assembled monolayers on gold and silicon surfaces

Formation, structure, and reactivity of amino-terminated organic films on silicon substrates

“…Most conventional FTIR data acquisition techniques include transmission [31,32], external reflection [33][34][35][36][37], and internal reflection [38,39]. Both transmission and external reflection methods generally produce infrared spectra with a low signal-to-noise ratio.…”

“…APTES films on silicon substrates have been characterized by numerous analytical techniques including X-ray photoelectron spectroscopy (XPS) [17,18,[27][28][29][30], Fourier transform infrared spectroscopy (FTIR) [31][32][33][34][35][36][37][38][39], ellipsometry [17,22,40], scanning probe microscopy [8,17,28,29], and contact angle measurements [18,30,41,42]. In particular, Fourier transform infrared spectroscopy with various sampling techniques has been popularly used to extract structural information regarding organic films of various thicknesses on silicon wafers.…”

Carbohydrate Arrays as Tools for Glycomics

“…[19] Subsequently, several SAMs were formed using thioglucose monosaccharides. [20] Characterization by reflection absorption infrared spectroscopy (RAIRS) [21] indicated that the orientation of the carbohydrates in each SAM was dependent on the anomeric thiol moiety. Thus, the nonreducing end of mannose was appropriately displayed to allow the lectins access to each monosaccharide unit.…”

Kohlenhydrat-Arrays: Hilfsmittel für die Glycomik

“…Später wurden mehrere SAMs aus Thioglucose‐Monosacchariden gebildet 20. Ihre Charakterisierung durch Reflektionsabsorptions‐Infrarotspektroskopie (RAIRS) ergab,21 dass die Orientierung der Kohlenhydrate in jeder SAM von der anomeren Thiolgruppe abhängt. Demzufolge wurde das nichtreduzierende Ende der Mannose so präsentiert, dass die Lectine jede Monosaccharideinheit erreichen konnten.…”
