From: Combined Labelled and Label-free SERS Probes for Triplex Three-dimensional Cellular Imaging
(A) Time-dependent SERS images (30 × 30 pixel) of HeLa cells incubated with CV- and CVa-coated AuNPs after 0, 1, 3 and 6 h of interaction with 30 μM Triton X-100. (B) Time-dependent SERS images of HeLa cells with added label-free nucleus-targeting AuNPs, after 1, 3, 6, 2, 24 and 48 h of interaction with 30 μM Triton X-100. A laser power of 3.0 mW was chosen and each pixel was exposed for 1 s (scale bar ≡ 4 μm).
