Strong and Weak Coupling Nanophysics with Free Electron Beams

open access: yesAdvanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Dual‐Modality Detection of Intracellular Nanoparticles via Smart Polymer‐Enhanced SERS and Hyperspectral Microscopy Detection

open access: yesAdvanced Optical Materials, EarlyView.
Dual‐imaging strategy for PAP‐functionalized gold nanoparticles (PAP@Gold NPs) in HeLa cells. Fast screening is achieved via hyperspectral microscopy based on light reflection to track nanoparticle localization. Accurate detection is performed through SERS microscopy, leveraging the plasmonic enhancement of the PAP polymer signal for precise location ...
