High-specificity SERS sensing with magnet-powered hierarchically structured micromotors

Dec 10, 2024 | opg.optica.org | Xiao Tang |Leilei Lan |Jiawei Wang |Teng Qiu

This work reports a hierarchically structured micromotor (HSM) surface-enhanced Raman scattering (SERS) platform comprising 3D tubular configurations with nanostructured outer walls. The HSMs can be powered by an external magnetic field in solution to enrich molecules with promoted adsorption efficiency. The nanostructured outer wall serves as containers to collect molecules and produce strong localized surface plasmon resonance to intensify Raman of the enriched molecules.
