The bio‐enabled synthesis of a novel class of surface enhanced Raman scattering probes is presented for functional imaging with built‐in and accessible electromagnetic hotspots formed between densely packed satellites grown on a plasmonic core. The superstructures serve as nanoscale sensors to spatiotemporally map intravesicular pH changes along endocytic pathways inside live cells.
