Summary: This study presents a novel surface-enhanced Raman scattering (SERS) spectroscopy platform for the dynamic sensing of biothiols. By using colloidally stable silver nanoparticles clusters equipped with a specifically designed azobenzene derivative, significant spectral changes can be observed in the presence of small biothiols, which can be quantitatively correlated with the biothiol content.

Summary: DNA origami technology enables precise assembly of chemical entities at the nanoscale, creating sophisticated functional materials. By assembling Au or Ag nanoparticle dimers, a versatile DNA origami nanofork antenna (DONA) has been developed, achieving signal enhancements in surface-enhanced Raman scattering (SERS) up to 10(11). Using the DNA origami structure, single-molecule SERS measurements of three dyes, cytochrome c, and horseradish peroxidase proteins have been successfully demonstrated.

Summary: This study presents the optical response of spherical CdSe nanocrystals using SERS and TERS techniques, achieving significant enhancement of optical phonons by selecting appropriate plasmonic substrates. Combining Raman scattering with atomic force microscopy offers nanoscale spatial resolution for investigating phonon properties. Gap-mode TERS further enhances Raman scattering of CdSe NCs' optical phonon modes with nanometer spatial resolution, providing new pathways for optical characterization and phonon spectrum details at the nanometer scale of single semiconductor nanostructures.

Summary: The study focuses on the plasmonic coupling between noble-metal and semiconductor nanostructures, and reveals the enhanced charge transfer and surface-enhanced Raman scattering (SERS) signals in a designed W18O49/Ag heterostructure. A new coupled-plasmon-induced charge transfer mechanism is proposed, providing insight for further studies on plasmonic effects and interfacial charge transfer in metal/semiconductor heterostructures.

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: This study investigates the enhancement effect of plasmonic gratings in nonlinear surface-enhanced coherent anti-Stokes Raman scattering (SECARS) using the platform of plasmonic Doppler grating (PDG). The PDGs spatially separate the input and output enhancement, allowing for observation and comparison of overall enhancement from different combinations of individual input and output beams. The results indicate that enhancement in the pump and anti-Stokes beams plays a more critical role in the overall enhancement than that in the Stokes beam.

Summary: Tuning and controlling the plasmon coupling of noble metal nanoparticles are crucial for enhancing their responses in near-field and far-field. A novel heterogeneous plasmonic assembly with a controllable hot spot model was proposed in this work, showing significant enhancement for SERS behavior in point-to-facet hotspots. The binary assemblies of Au NS doping in Au@Ag NCs demonstrate excellent sensitivity and high reproducibility in the identification of ketamine, indicating a new avenue for fabricating plasmonic metal materials with collective LSPR properties and sensitive SERS behavior.

Summary: This work provides an overview of the development and application of surface-enhanced Raman scattering (SERS) and plasmonic nanoplatforms, including various sensing platforms for monitoring genomic biomarkers, infectious diseases diagnostics, and cancer biomarker detection. It also presents applications of plasmonic AuNS in bioimaging, photothermal therapy, and immunotherapy. An interesting advancement called Synergistic Immuno Photothermal Nanotherapy (SYMPHONY) combines AuNS-mediated PTT with immunotherapy to enhance efficacy.

Summary: A versatile generation of plasmonic nanoparticle dimers for surface-enhanced Raman scattering (SERS) is presented, which combines a DNA origami nanofork and spherical and nonspherical Au or Ag nanoparticles. By optimizing the plasmonic nanoparticle dimers for a specific excitation wavelength in SERS, the structures and measurement conditions with the highest SERS enhancement factors (EFs) suitable for single-molecule SERS (SM-SERS) are identified. Anisotropic nanoparticles with sharp edges, such as nanoflowers, increase the probability of placing single molecules in strongly enhancing hot spots for SM-SERS. The combination of a Ag nanoparticle and a Au nanoflower is the most versatile plasmonic dimer structure for SERS.
