Raman spectroscopic studies of diamond in Intralipid.

Raman spectroscopic measurements were performed to determine the presence of a diamond located within an Intralipid scattering medium. The Raman signature of the diamond was recorded for varying thicknesses and concentrations of the Intralipid by use of a 514-nm argon-ion laser and a cw 785-nm Ti:sapphire laser. Results show how Raman spectroscopy can be used as a diagnostic tool for identifying objects embedded within scattering media. In particular, future applications could include tissue diagnostics performed in vivo.
