Through the capture of a target molecule at metal surface with highly confined electromagnetic field induced by plasmon, enhanced Raman spectroscopy (SERS) emerges as spectral analysis technology high sensitivity. However, accurate SERS identification gaseous low density and velocity is still challenge due to its difficulty in capture. In this work, flexible paper-based plasmonic metal–organic framework (MOF) film consisting Ag nanowires@ZIF-8 (AgNWs@ZIF-8) fabricated for detection molecules. Benefiting from micronanopores generated nanowire network ZIF-8 shell, effective achieved, spectrum obtained MOF film. With optimal structure parameters, spectra 4-aminothiophenol, 4-mercaptophenol, dithiohydroquinone demonstrate that has good performance, which could maintain obvious signals within 30 days during reproducible detection. To realize molecules, deep learning performed based on mixed analyte porous The results point out an artificial neural algorithm identify aldehydes (gaseous biomarker colorectal cancer) simulated exhaled breath accuracy 93.7%. integration sensors offers promising new approach noninvasive cancer screening.

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.
