Adsorption of seleno-l-cystine on silver electrode surfaces investigated by surface-enhanced Raman scattering

Electric Field-induced Charge Transfer of (Bu4N)2[Ru(dcbpyH)2-(NCS)2] on Gold, Silver, and Copper Electrode Surfaces Investigated by Means of Surface-enhanced Raman Scattering

“…7 The analysis of spectral features has provided information on adsorption, chemical reactions, and vibrational structures on surfaces. [8][9][10][11][12][13][14] Self-assembly methods represent a unique way to create well-defined nanostructures and thus control surface properties. 15 Characterization of self-assembled monolayers (SAMs) can provide detailed information on the chemical interactions and transformations occurring at surfaces.…”

Stimulus-responsive surface-enhanced Raman scattering: a “Trojan horse” strategy for precision molecular diagnosis of cancer

“…In detail, the Raman peaks at 747, 855, 941, 1173, 1250, 1300, 1365, 1396, 1444, 1579 and 1657 cm À1 showed distinctive changes in spectral intensity (Table 1). [42][43][44][45][46] Among them, the peaks at 855 and 941 cm À1 are assigned to carbohydrates (red bars); 46,47 the peaks at 1300, 1444 and 1657 cm À1 belong to fatty acids (yellow bars); 45 and the peaks at 747, 1173, and 1365 cm À1 are related to lactic acids, urea, and creatinine, respectively (green bars). [48][49][50][51] Aer comparing the Raman spectra of tumors in the two groups, we found that the intensity ratios of the peaks at 1444 and 1000 cm À1 have a signicant difference.…”

Novel high-temperature and pressure-compatible ultrasonic levitator apparatus coupled to Raman and Fourier transform infrared spectrometers

“…The vibrational assignments of the Raman bands in cystine are given in Ref. 34. The new peak at 515 cm −1 in the irradiated cysteine spectrum is likely due to the S-S stretching mode of the C-SS-C disulfide bridge in cystine (see Fig.…”

“…The cystine peak assignments shown are from Ref. 34. and after irradiation (bottom spectrum) by the CO 2 laser.…”
