Raman imaging gives new hope for cancer diagnosis

Pop over to Chemistry World to read how combining two Raman spectroscopic imaging techniques could offer a valuable tool for future disease diagnosis.

“[The] work solves a limitation of Raman imaging by developing strategies to go from about 5 to 50mm depth penetration,” says Sanjiv Sam Gambhir, director of the Molecular Imaging Program at Stanford University.

Co-authored by Analyst Board members Duncan Graham and Pavel Matousek, the paper describes how putting SERS together with deep Raman spectroscopy can enable non-invasive analysis of multiple antibodies for different diseases tagged to nanoparticles.
