Abstract
Metabolite-related biomarkers play crucial roles in the medical field, which can be used as diagnostic tools for disease diagnosis and therapeutic evaluation, even the mechanisms of diseases. Nevertheless, conventional diagnostic techniques might face restrictions regarding the range of metabolites they can detect and the precision of their measurements. Moreover, the handling, preparation, and preservation of specimens can greatly influence the analytical outcomes. The emergence of surface-enhanced Raman scattering (SERS) technology offers new advantages for the detection of metabolomic markers. Known for its high sensitivity and non-destructive detection methods, SERS uses metal nanoparticles to significantly amplify spectral signals, enabling the detection of low-abundance biomolecules. This review discusses the application of SERS technology in the design and development of nanoprobes for biological analysis and detection at various dimensions and levels of disease. These innovations are intended to overcome the constraints of conventional diagnostic techniques, facilitating the prompt identification and intervention for illnesses.
