Effects of Chemical Fixation on Stimulated Raman Scattering Microscopy

Abstract Stimulated Raman scattering (SRS) microscopy enables label-free imaging of cells and tissues in their native state with chemical specificity. However, there are often experimental advantages of chemical fixation of samples prior to imaging, which can introduce perturbati...

How β -Ionone Ring Dynamics and Conformational Heterogeneity Control Carotenoid Photophysics

Abstract Carotenoid ultrafast photophysics has been studied for decades, but fully resolving their excited-state relaxation mechanisms remains a central, driving pursuit. Here, we investigate mini-β-carotene (m5) as a tractable model system, coupling high time-resolution transien...
