PESRS mapping of adenine generated from stressed bacteria. a A schematic of PESRS mapping of adenine generated from stressed bacteria. b The PESRS spectra of S. aureus washed and kept in water for 1 h. The PESRS spectra of S. aureus obtained immediately (0 h) after washing. Numbers 1, 2, 3 represent measurements at three locations on surface. No denoising applied. c Denoised PESRS image of starved S. aureus placed on the plasmonic substrate. The image area is 30 μm × 30 μm. d Single-pixel PESRS spectra of S. aureus on plasmonic substrate obtained from spot 1 and 2 indicated in panel c.
