Progress on fiber-based surface-enhanced Raman scattering substrates

In view of the poor stability and inconvenient detection process of traditional urface-enhanced Raman scattering (SERS) substrates, the current research and application progress in fiber-based SERS substrates in the field of trace detection were reviewed in this and the advantages of flexible SERS substrates were summarized. The mechanisms of SERS were firstly introduced briefly, including electromagnetic enhancement and chemical enhancement. Secondly, the fabrication methods and practical application of fiber-based SERS, fabric-based SERS, and nanofibrous membranes SERS substrates were reviewed. Emphasis was placed on the research status of fabric-based SERS substrates and their challenges and opportunities in future detection applications. Based on the highly sensitive and flexible detection of fabric-based SERS materials, the potential application as a wearable sensor for instant detection and environmental monitoring was discussed, which leads to new ideas of creation of smart textiles.
