Label free bioimaging using nonlinear coherent Raman microscopy

Raman imaging visualizes the biomolecule without staining; however, the low cross section of Raman scattering requires long observation time. We have developed a nonlinear Raman microscope and endoscope for fast biomolecular imaging without staining. In the presentation, I would like to talk about the present status of nonlinear Raman imaging and medical applications.
