Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

Advanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

A SERS‐Based Antibody‐Aptamer Sandwich Assay for Extracellular Vesicle‐Associated Tau Detection Using Gold Nanoparticles

Advanced Sensor Research, EarlyView.
Tau protein plays a critical role in the pathology of Alzheimer's disease, utilizing extracellular vesicles (EVs) as a mechanism for intercellular transmission. This study develops a highly sensitive sandwich assay biosensor for detecting and quantifying tau‐associated EVs using surface‐enhanced Raman spectroscopy (SERS).
