Summary: A novel dual biomimetic recognition-driven plasmonic nanogap-enhanced Raman scattering strategy was reported for ultrasensitive protein fingerprinting and quantitation. By trapping target proteins into plasmonic nanogaps, ultra-high Raman signal amplification was achieved, along with a ratiometric assay for robust quantitation.

Summary: This study presents a template-assisted method for synthesizing nanogap shell structures for biomolecular detections based on surface-enhanced Raman scattering. The fabricated silver nanogap shells (Ag NGSs) showed high enhancement factor and good signal uniformity, enabling multiplex biomolecular detection and imaging. The research demonstrates the potential of highly sensitive Ag NGS nanoprobes for point-of-care diagnostics and appropriate treatment options.

Summary: In this study, we for the first time observed and considered the plasmonic coupling between noble-metal and semiconductor nanostructures in metal/semiconductor heterostructures, using a W18O49/Ag heterostructure composed of Ag nanoparticles and W18O49 nanowires. The heterogeneous structure exhibited a broad and strong surface plasmon resonance (SPR) absorption in the visible wavelength range. Surface-enhanced Raman scattering (SERS) was used to investigate the interactions between metal SPR, semiconductor SPR, and the heterostructure's charge transfer process, revealing that the coupled SPR enhanced the heterostructure's internal charge transfer and SERS signals. A new coupled-plasmon-induced charge transfer mechanism was proposed to explain the improved charge transfer efficiency. This work provides insights for further studies on plasmonic effects and interfacial charge transfer in metal/semiconductor heterostructures.

Summary: Surface-enhanced Raman scattering (SERS) is a fascinating phenomenon that enhances the Raman signals of molecules by creating hot spots. In this study, a high-performance Ag/ZIF-8 SERS substrate is fabricated using a simple two-step method. Plasmonic nanogaps are created between the Ag nanocap and the Ag layer on the substrate, resulting in greatly enhanced electromagnetic (EM) field and preconcentration effect. The measurement results show high SERS enhancement factor, low detectable concentration, and low relative standard deviation, suggesting the potential of this substrate for molecular detection.

Summary: Research shows that plasmonic supercrystals, with a high density of hotspots, are an excellent platform for enhancing vibrational spectra by increasing the cross section of Raman scattering and infrared absorption. The study demonstrates that the intensity of surface-enhanced Raman scattering inside the crystal is uniform and predictable, with supercrystal polaritons inducing resonances in the enhanced cross section for both Raman scattering and infrared absorption. The enhancement of infrared absorption within supercrystals is attributed to the combined effects of hotspot formation and the excitation of standing polariton waves.

Summary: This study demonstrates that holes induced by plasmon coupling can accumulate significantly at the plasmonic Au nanoparticle dimer/TiO2 interface in the nanogap region, leading to a substantial acceleration of the water oxidation reaction. The local accumulated hole density is found to be proportional to the square of the local near-field enhancement, providing insights into the spatial distribution of charges in plasmonic systems and the role of local charge density at reaction sites in plasmonic photocatalysis.

Summary: A bimodal imaging method was developed to spatially resolve and correlate SERS and Mie scattering signals. By examining different types of nanoparticle assemblies, distinct behaviors between intra- and interparticle nanogaps were observed. The study demonstrated the potential of this dual-imaging approach for improving the reliability of SERS measurements.

Summary: The study reports the fabrication of a highly efficient Ag SERS substrate and verifies the existence of the Raman A(1g) mode in rutile SnO2 quantum dots. It also discovers the presence of an intense IR-active E-u (TO) mode in 25 nm size crystalline SnO2, suggesting an explanation based on the gradient-field Raman (GFR) effect.
