From: Combined Labelled and Label-free SERS Probes for Triplex Three-dimensional Cellular Imaging
Multi-targeting SERS imaging of a HeLa cell treated with both label-free membrane- and nucleus-targeting AuNPs.
(A) SERS image and (B) bright-field image of the investigated HeLa cell. (C) SERS spectra obtained from different positions within the cell such as membrane (blue), cell nucleus (red) and the surrounding environment (black) show significant differences in terms of their intensity and peak positions (scale bar ≡ 4 μm).
