MXene-Based Micromotors: Active Molecular Enrichment and Selective Raman Enhancement
This Letter introduces MXene-based rod-like micromotors, consisting of assembled Fe<sub>3</sub>O<sub>4</sub>@Ti<sub>2</sub>C core-shell nanospheres, that leverage external magnetic fields for active molecular enrichment and selective surface-enhanced Raman scattering (SERS) sensing. These micromotors enhance SERS performance by concentrating target molecules directly onto MXene surfaces during movement, enabling rapid and precise detection. Our investigation reveals how these micromotors optimize SERS through effective molecular manipulation and explores the selective Raman enhancement facilitated by the MXene-based platforms, demonstrating their significant potential in analytical applications.
