Surface-enhanced Raman scattering (SERS), a powerful spectroscopic technique owing to its abundant vibrational fingerprints, has been widely employed for the assay of analytes. It is generally considered that one critical factors determining SERS performance property substrate materials. Apart from noble metal substrates, non-noble nanostructured materials, as emerging new have extensively studied research by virtue their superior biocompatibility, good chemical stability, outstanding selectivity, and unique physicochemical properties such adjustable band structure carrier concentration. Herein, in this review, we summarized on analytical application substrates three aspects. Firstly, started with an introduction possible enhancement mechanism substrates. Then, guideline design, several main types including carbon nanomaterials, transition dichalcogenides (TMDs), oxides, metal-organic frameworks (MOFs), carbides nitrides (MXenes), conjugated polymers were discussed. Finally, especially emphasized application, detection pollutants biomarkers. Moreover, challenges attractive prospects practical proposed. This work may arouse more awareness material-based bioanalysis.

Surface-enhanced Raman scattering (SERS) enables pesticide residue monitoring to become facile and efficient. In this study, a core-shell structured gold nanoparticles@ZnCo metal-organic framework (AuNPs@ZnCo-MOF) SERS substrate was designed successfully synthesized for efficient selective detection of thiram. The bimetallic ZnCo-MOF shell can not only enrich the targeted molecules in electromagnetic field because its excellent absorptive capacity, but also act as stabilized matrix protecting AuNPs from aggregation. AuNPs@ZnCo-MOFs exhibited high enhancement factor (EF) 3.51 × 10

Given the prevalence of food safety, online monitoring quality is essential. Surface-enhanced Raman scattering (SERS) has excellent sensitivity and molecular fingerprinting capabilities in analytical fields, but its accuracy safety severely constrained, particularly for gaseous molecules. To further develop SERS technique sensing, this work, a slippery liquid-infused porous surface (SLIPS) platform was developed real-time change molecules shrimp spoilage processes. In order to monitor pH biogenic amine (BAs), 4-mercaptopyridine (4-Mpy) 4-mercaptobenzaldehyde (4-MBA)-functionalized ZIF-8-encapsulated gold nanostars (AuNS@ZIF-8) were utilized as response probes, respectively. Due superior molecule trapping ability ZIF-8 enrichment effect SLIPS substrates, use 4-Mpy 4-MBA-functionalized AuNS@ZIF-8-SLIPS substrates exhibited sensing performance putrescine The detection ranges BAs 4.0-9.0 10-7-10-3 (v/v) with RSDs 4.1% 4.2%, Furthermore, used at 25 °C 4 real time. Hence, membrane strategy can serve promising alternative ensure accurate, real-time, non-destructive freshness.
