Enrichment-Sensing All-in-One Strategy Integrated in the La(OH)3-Au@AgNPs Substrate for Rapid Surface-Enhanced Raman Spectroscopy Analysis of Purine Components

“…In the XPS spectra of La­(OH) 3 –Au seeds and La­(OH) 3 –AuNPs, the characteristic peaks attributed to Au 4f 5/2 and Au 4f 7/2 can be observed at 87.68 and 84.08 eV, respectively (Figure S3C). The characteristic peaks of Ag 3d 5/2 and Ag 3d 3/2 can be observed at the binding energies of 367.58 and 373.58 eV, respectively, in the XPS spectra of La­(OH) 3 –Au@AgNPs (Figure S3A).…”

“…In the XPS spectrum of La(OH) 3 , it is observed that the binding energy is attributed to La−OH at 834.68 and 838.68 eV 30 peaks attributed to Au 4f 5/2 and Au 4f 7/2 can be observed at 87.68 and 84.08 eV, 32 respectively (Figure S3C). The characteristic peaks of Ag 3d 5/2 and Ag 3d 3/2 can be observed at the binding energies of 367.58 and 373.58 eV, 33 respectively, in the XPS spectra of La(OH) 3 −Au@AgNPs (Figure S3A). In addition, UV−vis spectroscopy was used to monitor the preparation of La(OH) 3 −Au@AgNPs (Figure 2C).…”

Prospects for the use of laser spectroscopy to characterize dye degradation photocatalyst nanoparticles: a review

“…131 Flower-like Au@MoS 2 /Ag NPs with SERS substrates exhibiting satisfactory regenerative properties were developed by Liu et al 132 Shafi et al introduced new recyclable bifunctional structured SERS substrates that provide a unique avenue for enhancing SERS efficiency. 133 Zhang et al systematically discussed the problem of non-recyclable SERS substrates and summarized the methods used for their application. 134 These works provide a wide range of research ideas for the study of photocatalyst nanoparticles in metal–semiconductor hybrids using SERS.…”

ZnO@Ag-Functionalized Paper-Based Microarray Chip for SERS Detection of Bacteria and Antibacterial and Photocatalytic Inactivation

“…11,12 Significantly, when noble metal NPs are compounded with semiconductor NPs, the composite can override both metal and semiconductor NPs, resulting in novel electronic and optical properties. 13 The photogenerated carriers generated by the semiconductor material can be trapped by the noble metal NPs, which will increase the rate of photogenerated carrier separation and migration to reach the goal of improving the interfacial charge transfer efficiency. 14 Noble metal NPs can also act as the trapping centers for photogenerated electrons, thus inhibiting the compounding of photogenerated electron− hole pairs, which can effectively improve the photocatalytic performance of semiconductor materials.…”
