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 ...

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers

Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.

Progress in Surface‐Enhanced Raman Scattering‐Based Volatile Organic Compounds Detection: Materials, Application, and Prospects

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

Single‐Molecule Imaging and Spectroscopy Enables Quantification of Location‐Dependent Light–Matter Interactions on Nanoantennas

Small Science, Volume 6, Issue 3, March 2026.
The fluorescence intensity as well as the spectral shape of the emission of single dye molecules strongly depend on the molecules’ exact position relative to plasmonic nanoparticles in hybrid systems. By point‐spread function modification analysis, the vertical binding location of single fluorophores on gold nanocones is obtained and correlated to both

Focused Thermal Emission From a Radiative Metasurface

Small Structures, Volume 7, Issue 3, March 2026.
MIM‐type metasurfaces, consisting of metal‐dielectric‐metal nanostructures, are promising materials for achieving highly efficient photothermal conversion. By introducing a structural arrangement inspired by metalens, which can focus light using a two‐dimensional lens, into this structure, we have achieved filter‐less light‐focusing operation.
