Integration of multidimensional studies in tissue optics, mechanobiology and optical clearing will be achieved by interfacing nonlinear optical microscopy (NLOM) with electron microscopy, genomic profiling, biomechanical stress-strain and clinical, in vivo measurements. NLOM is a non-destructive, laser scanning microscopy technique, which can image (sub-) cellular processes in a thick, living tissue specimen over the course of a biological event without fixing, staining or sectioning. Specific imaging of tissue constituents by NLOM will be accomplished via nonlinear optical spectroscopy (e.g., second-harmonic generation and two-photon excited fluorescence). NLOM will be used to monitor tissue structure, organization, composition with (sub-) cellular resolution and changes due to altered mechanical and chemical environments and growth and remodeling.
