Photoswitchable SRS signal of fixed HeLa cells stained with DAE620 observed at the Raman on-resonance wave number
Description
Photoswitchable SRS (stimulated Raman scattering) signal of fixed HeLa cells stained with DAE620 (a bright diarylethene–based Raman probe) observed at the Raman on-resonance wave number (1503 cm^{-1}). The Raman probe was switched-on with 375 nm light and switched-off with 640 nm light.
