From: Rapid in vivo lipid/carbohydrate quantification of single microalgal cell by Raman spectral imaging to reveal salinity-induced starch-to-lipid shift

Fig. 2

The Raman spectra of control, nitrogen-depleted (3-day nitrogen depleted as N3, 5-day nitrogen depleted as N5), and nitrogen-depleted plus salt-stressed (2% NaCl N5 and 5% NaCl N3) algal cells. The green labels highlight Raman bands that we compare between different culturing conditions. The Raman bands that we discuss only in a specific spectrum are indicated by the black indicator with their Raman shift value. The pink area alongside the spectra represents the spectral standard deviation within a single algal cell
