Functional Interfaces

Multimodal nonlinear imaging constitutes a contemporary approach to investigate the morphochemistry of complex samples noninvasively and without administration of external labels. Here we discuss our recent success in jointly using various nonlinear microspectroscopic approaches such as coherent anti-Stokes Raman scattering (CARS), two-photon fluorescence (TPF) and second-harmonic generation (SHG) to study the chemical composition of surgically removed tissue sections from laryngeal carcinoma. In particular it will be shown how multimodal nonlinear imaging can be employed to study the structural and chemical development of disease formation as well as to monitor the clinically important aspect of tumor boundary detection
