Fig. 3. (A) Schematic illustration of the targeting of live cells by SERS agents. (B) Bright-field and spatially mapped 1340 cm–1 Raman peak intensity images of PSMA+ PC3 PIP cells in the absence/presence of SERS agent (50 pM). The SERS images were constructed on the basis of the integrated intensity of the 1340 cm–1 Raman band.
