Carrier Funneling and Luminescent Collimation for Extreme Diffuse Light Concentration

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
Luminescent concentrators show performance millions of times below their thermodynamic limit because of their inefficient design. Carrier funneling combined with luminescent collimation decouples concentration from propagation distance, breaking the practical limitation of current approaches.

Engineering Disordered Many‐Particle Plasmonic Nanoclusters for Wafer‐Scale Uniform and Giant Electromagnetic Field Enhancement

Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.
This work presents a lithography‐ and etching‐free dewetting strategy that assembles many‐particle gold nanostructures into uniform plasmonic substrates at the wafer scale. By forming satellite nanoparticles between larger ones, the method achieves giant and highly reproducible electromagnetic enhancement.

Interfacial Regulation–Driven Dual‐Enrichment SERS Coupled With Deep Learning Enable Ultrasensitive and In Situ Identification of Microplastics in Natural Waters

Small, Volume 22, Issue 44, 7 August 2026.
A membrane‐confined SERS platform constructs a dense network of vertical hotspots using PSS‐Na‐modified Au@Ag nanocubes for sensitive and reproducible microplastic detection in complex environmental water matrices. Coupled with an attention‐based 1D‐CNN, it enables accurate polymer identification and semi‐quantitative mixture prediction for intelligent

Silica/Nanographene Oxide Nanocomposites Decorated With Au@Ag Nanoparticles as Surface‐Enhanced Raman Scattering Tags for Highly Sensitive Quantitative Lateral Flow Immunoassays

Small Structures, Volume 7, Issue 8, August 2026.
A silica (SiO2)/nanographene oxide (nGO) nanocomposite decorated with Au@Ag nanoparticles (SGO@Au@Ag NPs) was developed as a highly sensitive SERS tag. The nanocomposite exhibits SERS signal enhancement by combining electromagnetic hot spots generated by Au@Ag NPs with the functional advantages of GO.
