Catalysis stands as an indispensable cornerstone of modern society, underpinning the production over 80% manufactured goods and driving 90% industrial chemical processes. As demand for more efficient sustainable processes grows, better catalysts are needed. Understanding working principles is key, last 50 years, surface-enhanced Raman Spectroscopy (SERS) has become essential. Discovered in 1974, SERS evolved into a mature powerful analytical tool, transforming way which we detect molecules across disciplines. In catalysis, enabled insights dynamic surface phenomena, facilitating monitoring catalyst structure, adsorbate interactions, reaction kinetics at very high spatial temporal resolutions. This review explores achievements well future potential field catalysis energy conversion, thereby highlighting its role advancing these critical areas research.

Respiratory syncytial virus (RSV) poses a significant threat to the health of infants, children, and elderly, as now there is lack effective therapeutic drugs. To tackle this challenge, chiral vanadium trioxide nanoparticles (V2O3 NPs) with particle size 2.56 ± 0.34 nm are successfully synthesized, exhibiting g-factor value 0.048 at 874 in terms circular dichroism. Under 808 light irradiation, these V2O3 NPs demonstrated selective cleavage RSV pre-fusion protein (RSV protein), effectively blocking its conformational rearrangement preventing infection both vitro vivo. Experimental analysis revealed that specifically bind functional domain spanning from aspartate200 (D200) asparagine208 (N208) primary sequence protein. Notably, L-V2O3 exhibited higher affinity, which 4.06 times D-V2O3 13.55 DL-V2O3 NPs.

Sensitive recognition of enantiomer has aroused extensive interest due to its importance in diverse fields ranging from pharmaceuticals catalysis and biomedicine. Chiral surface-enhanced Raman scattering (SERS) by chiral plasmonic substrates emerged as a promising tool for the enantiomers with high sensitivity well molecular fingerprinting capability. However, impact states including surface packing density configurations surface-adsorbed molecules on SERS been largely unexplored. Herein, we demonstrate that nanoparticles (NPs) is sensitively dependent coverage enantiomers. Au helical nanocubes tunable optical properties intense near-field enhancements were chosen SERS. By changing concentration structure enantiomers, revealed. Finally, use achiral internal spacers achieving ultrasensitive detection enantiomer. The insights gained this work not only shed light underlying mechanisms dictating NPs but also strongly suggest approach sensitive chirality using spectroscopy.
