Vibrational spectroscopy provides chemical information from all materials, and is well suited to biological samples. Diagnoses cancerous tissue, and non-invasively characterizes live cells.
CARS microscopy gives 4-5 orders of magnitude more signal than standard Raman spectroscopy. Produces high resolution, label-free chemical images of live cells and tissue in seconds.
CARS microscopy, two-photon fluorescence (TPF), second harmonic generation (SHG), sum frequency generation (SFG), and fluorescence lifetime imaging (FLIM): all on the same microscope.
Combining optical spectroscopy with Atomic Force Microscopy to achieve local Raman spectroscopy on the scale of ~10 nm. Nano-scale fluorescence and (coming soon:) CARS microscopy.
