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.

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 ...

Plasmonics‐Enhanced Characterization of Cervid PrP (87–114) Fragment Aggregates in Solution
Multimodal nanophotonics platform combining plasmon‐enhanced imaging, label‐free SERS, and optical staining reveals new insights into the aggregation of the cervid PrP (87–114) fragment, an amyloidogenic sequence linked to chronic wasting disease susceptibility.ABSTRACTWe performed a multimodal characterisation of self‐assembled fibrillar aggregates ...

When a uniform field interacts with a complex medium, it becomes scattered into a nonuniform distribution. A mode‐integration metamaterial employs its intrinsic controlled disorder to coherently reorganize and integrate the scattered field components into a tailored modal output, establishing a new paradigm for programmable modal coupling and versatile
