Raman image obtain of S. obliquus. a Raman spectra after pretreatment locate at the black asterisk in the inset image. The left inset image shows the bright-field image of a single cell of S. obliquus, and the other inset image shows partial enlarged detail of lipid characteristic peaks. b, c Raman images of the same cell at b 1445 cm−1, c 1266 cm−1. d Raman image and bright-field image of quadruplet cells of S. obliquus at 1445 cm−1
