In the battle against brain cancer, doctors now have a new weapon: an imaging technology that will make brain surgery dramatically more accurate by allowing surgeons to distinguish between brain tissue and tumors at a microscopic level.

Called SRS microscopy — short for stimulated Raman scattering — a team of researchers that included Xiaoliang Sunney Xie, the Mallinckrodt Professor of Chemistry and Chemical Biology, and Minbiao Ji, a postdoctoral fellow in chemistry and chemical biology, were able to “see” the tiniest areas of tumor cells in brain tissue, and to distinguish tumor from healthy tissue in the brains of living mice.
