Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

Advanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐
