Magnetic Nanomotor-Based Maneuverable SERS Probe

Figure 1

Preparation and characterization of “rod-like” magnetic nanomotor-based SERS probes (MNM-SP). (a) Schematic illustration of the fabrication and SERS sensing of the MNM-SP. SEM images of (b) Fe3O4 nanoparticles, (c) silica-coated magnetic nanorods, and (d) magnetic rod decorated with Ag nanoparticles, respectively. (e) EDS elemental mapping of “rod-like” magnetic SERS probes. Raman spectra of different concentrations of (f) CV and (g) R6G, respectively.
