Figure 1. Schematic illustration comparing conventional SERS sensing platforms and the proposed ASC-PR paradigm. (A) Traditional SERS probes; (B) Design of a the MagSense-Bot and its merits; (C) Actuation-sensing coupled plasmonic robot system that can realize active navigation and localized chemical interrogation. SERS: Surface-enhanced Raman scattering; ASC-PR: Actuation-Sensing Coupled Plasmonic Robotics.
