Application of nonlinear optical SFG spectroscopy to the spectral and spatial cartography of organic monolayers: study of the couplings between the vibrational and electronic properties at biological interfaces

Two colour sum frequency generation spectroscopy and imaging are used to characterise the vibrational and electronic properties and the molecular recognition processes in biological environment and on nanostructured arrays. The measurements are performed ex situ and in situ, with or without electrochemical control.
