WebOct 5, 2024 · Her research uses multimodal coherent Raman scattering and fluorescence imaging to monitor the interaction of cancer cells with the tumor microenvironment and provide read-outs of cancer phenotypes in real time. Other research is focused on exploiting the benefits of stimulated Raman scattering microscopy to monitor drug distribution … WebTo demonstrate how stimulated Raman scattering works, a green laser at 532 nm is focused into a cell of deuterium. The molecules of deuterium vibrate in such a way that the light changes into red (632 nm). Since red light has less energy than green light, the deuterium molecules take some of the green light's energy away in the process.
