Molecular Spectroscopy Workbench: Current Uses of Raman Microscopy in Biomedical Studies

[J. Raman Spectr] mapping, in combination with multivariate analysis, is known to provide useful images. But because of the weakness of the Raman process, the acquisition of these images is slow. Over the past 10 years or so, Sunney Xie's group at Harvard has been developing methods to acquire Raman images using multiphoton processes. These processes have been known for quite some time, but with the availability of evolving laser technology, implementation possibilities have multiplied.
