Chemometric evaluation of temperature-dependent surface-enhanced Raman spectra of riboflavin: What is the best multivariate approach to describe the effect of temperature?

Popis výsledku v původním jazyce

Riboflavin is an essential nutrient involved in energetic metabolism. From analytical point of view, riboflavin can be used as an active part of sensors. In biological environment, metal substrates coated with riboflavin are exposed to temperatures thatare different from room temperature. Hence, it is important to describe the influence of temperature on adsorbed molecules of riboflavin, especially on orientation of molecules towards the metal surface and on stability of adsorbed molecular layer. Surface-enhanced Raman scattering spectroscopy is a useful tool for investigation of architecture of molecular layers adsorbed on metal surfaces. In this study, riboflavin was adsorbed on electrochemically prepared massive silver substrates that were exposedto temperature changes according to four different temperature programs. Raman spectra measured at different temperatures were compared considering positions of spectral bands, their intensities and bandwidths. It was found out that incre
