From: Study on the Visualization of Pigment in Haematococcus pluvialis by Raman Spectroscopy Technique

Concentration maps of spectral components representing carotenoids and astaxanthin in H. pluvialis cells (Note: Distribution of carotenoid was obtained by raman intensity at the C = C stretch bond, and distribution of astaxanthin was obtained by raman intensity at the C = C stretch bond combined with MCR-ALS model). (a–c) Raman images of cells under inductive conditions for 0, 24, 48, respectively.
