Among various optical methods, fluorescence imaging has been the most widely exploited thanks to its superior sensitivity and specificity, but the resolvable colors are restricted to 2-5 colors because of the intrinsically broad and featureless spectra. Recently, this fluorescent “color barrier” was broken and super-multiplex optical imaging became possible taking advantage of well-designed Raman probes. However, the acquisition of the super-multiplex images is still relatively slow which impedes wider applications. Here, we demonstrate fast super-multiplex organelle imaging with high-speed color switching and acquisition, which accelerates the imaging speed by 2 orders of magnitude. We applied it in imaging cytometry, tracing mitosis and fast organelle motions in live cells. We anticipate that high-speed supermultiplex optical imaging can expand to a much wider field of biological researches.
