Observation of Edge‐Confined Acoustic Hyperbolic Polaritons in van der Waals Materials

Advanced Science, Volume 13, Issue 14, 9 March 2026.
This work demonstrates a new type of light wave—edge‐confined acoustic hyperbolic polaritons—in hexagonal boron nitride on gold. These waves travel along crystal edges with nanoscale confinement and strongly interact with molecular vibrations, enabling highly sensitive detection of tiny molecular layers.

Trace Alloying Unleashed: AuPt Nanoalloys Strategy Preserves Plasmonic Properties on Au Nanobipyramids While Boosting Electron Transfer for Visible Light Ammonia Synthesis

Advanced Science, Volume 13, Issue 14, 9 March 2026.
Au nanobipyramids (Au NBPs) with distinct Pt configurations—dense Pt layers (Au NBPs@Ptd), sparse Pt clusters (Au NBPs@Pts), and trace AuPt alloy (Au NBPs@Au/Ptalloy) were engineered. Au NBPs@Au/Ptalloy exhibited optimal performance in the photoelectrocatalytic nitrite‐to‐ammonia conversion.

Periodic and Statistically Distributed Surface Texturing of Surface‐Enhanced Raman Spectroscopy (SERS) Sensors with Spatially Selective Signal Mapping

Advanced Physics Research, Volume 5, Issue 3, March 2026.
Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.

Rational Design and Functional Optimization of Surface‐Enhanced Raman Spectroscopy Substrates: From Material Engineering to Bioanalysis

ChemistryEurope, Volume 4, Issue 3, March 2026.
This review presents a rational design framework for high‐performance surface‐enhanced Raman spectroscopy (SERS) substrates enabling ultrasensitive detection. It first elucidates the dual enhancement mechanisms, namely the dominant electromagnetic enhancement arising from localized surface plasmon resonances and the complementary chemical enhancement ...

Reinforcement Learning Enabled Nanophotonic Devices

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components
