Abstract Surface-enhanced spectroscopy technology based on metamaterials has flourished in recent years, and the use of artificially designed subwavelength structures can effectively regulate light waves electromagnetic fields, making it a valuable platform for sensing applications. With continuous improvement theory, several effective universal modes have gradually formed, including localized surface plasmon resonance (LSPR), Mie resonance, bound states continuum (BIC), Fano resonance. This review begins by summarizing these core mechanisms, followed comprehensive overview six main surface-enhanced techniques across spectrum: fluorescence (SEF), Raman scattering (SERS), infrared absorption (SEIRA), terahertz (THz) sensing, refractive index (RI) chiral sensing. These cover wide spectral range address various optical characteristics, enabling detection molecular fingerprints, structural chirality, changes. Additionally, this summarized combined different enhanced spectra, integration with other advanced technologies, status miniaturized metamaterial systems. Finally, we assess current challenges future directions. Looking to future, anticipate that metamaterial-based will play transformative role real-time, on-site scientific, environmental, biomedical fields.
