Summary: Designing uniform plasmonic surfaces in a large area is crucial for surface-enhanced Raman scattering (SERS), and laser interference lithography (LIL) is a versatile tool for rapidly fabricating periodic patterns. The multi-exposure laser interference lithography (MELIL) method can produce nearly periodic profiles in all directions, leading to highly uniform Raman scattering in complex geometries. Additionally, the vacuum-free electroplating method enhances the performance of the process, providing a cost-effective alternative for SERS applications.

Summary: Anapole modes in all-dielectric nanostructures can be boosted through electromagnetic interactions beyond both near-field and far-field limits. Through analytical calculations and numerical simulations, it was found that electric dipoles associated with the anapole mode undergo retardation-related interactions with electric dipoles associated with a ring in the nanostructure, leading to efficiently enhanced responses. The near-field enhancement in a slotted silicon disk-ring nanostructure reached over 90 times, indicating the greatly enhanced anapole mode through electromagnetic couplings for potential applications in enhanced nonlinear photonics and near-field enhanced spectroscopies.

Summary: Despite the growing global production and use of plastics, which generates vast amounts of plastic waste and micmplastics in the marine environment, a new method based on plasmon-enhanced fluorescence (PEF) was developed to detect microplastics in highly diluted natural samples. The method utilizes gold nanopillar-based substrates to enhance the fluorescence emission signal from microplastics in water samples and has a low limit of detection and quantification. This new method enables the visualization of undyed microplastics in fluorescence microscopy, even particles and fibers too small to be imaged with conventional light microscopy, making it a valuable tool for microplastic research.
