We developed a multimodal optical metabolic imaging system that integrates SRS, MPF, and SHG, for studying aging and diseases. We quantitatively measured the metabolic dynamics in cells and animals under various conditions, and further combined deuterium oxide probing with stimulated Raman scattering (DO-SRS) for visualizing newly synthesized protein and lipid molecules, in addition to macromolecules (protein and lipid, NADH and Flavin, collagen) imaged with the label free multimodal microscopy.
