Abstract
We present a high-throughput multimodal Raman-fluorescence flow cytometer that produces simultaneous Raman and fluorescence excitation spectra at a demonstrated throughput of 100 events per second. Our method combines Fourier-transform coherent anti-Stokes Raman scattering with Fourier-transform two-photon excitation fluorescence, which produces broadband Raman spectra that span the biological fingerprint region and single-detector multicolor fluorescence via spectral analysis. As a proof-of-principle demonstration, we perform multimodal label-free analysis of stress response in the microalga Haematococcus pluvialis by Raman measurement of its secondary metabolite astaxanthin and two-color fluorescence measurement of chlorophyll and fluorescent chlorophyll catabolites under different stress conditions.
