Abstract Chiral metasurfaces, featuring customizable chiroptical response, have shown great potential across diverse applications, including optical sensing, chiral emission, and light spin detection. However, most previous studies focused on response stemming from the resonance of nanoresonators or their coupling. Here, capability controlling nonlocal for achieving versatile manipulation circular dichroism (CD) is demonstrated. A counterintuitive sign reversal CD realized by modulating collective interference plasmonic guided mode resonances (GMRs) within diatomic metasurfaces. The designed composed two nanoresonators, can effectively couple both orthogonal linear‐polarized components circularly polarized to same GMR. Through a simple adjustment spacing modulate between GMRs, continuous variation are achieved. Importantly, due fact that modulation GMRs does not impact resonant modes significant advantages metasurfaces in encryption experimentally This work introduces an effective approach without altering structural geometric chirality. It provides novel insights into exploring mechanisms holds promise applications sensing

Abstract Intrinsically chiral plasmonic nanomaterials exhibit intriguing geometry‐dependent chiroptical properties, which is due to the combination of features with geometric chirality. Thus, have become promising candidates for applications in biosensing, asymmetric catalysis, biomedicine, photonics, etc. Recent advances control and optical tuning intrinsically further opened up a unique opportunity their widespread many emerging technological areas. Here, recent developments are reviewed special attention given quantitative understanding structure‐property relationship. Several important spectroscopic tools characterizing chirality at both ensemble single‐particle levels also discussed. Three nanomaterials, including enantioselective sensing, highlighted. It envisioned that these advanced studies will pave way toward rational design desired properties diverse applications.

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. The precise cutting site located between amino acid residues leucine204 (L204) proline205 (P205), attributed reactive oxygen species (ROS) generated by photoinduced nanoparticles.
