Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes

Small, EarlyView.
This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, EarlyView.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

Small, EarlyView.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).

Notoginsenoside‐Fa mitigates vascular endothelial permeability via targeting SUGT1 to stabilize NLRP3 in a resting state

British Journal of Pharmacology, EarlyView.
Background and Purpose Notoginsenoside‐Fa (Noto‐Fa) is an emerging active compound derived from notoginseng with promise in treating cardiovascular diseases. The development of cardiovascular diseases is intricately linked to the damage of vascular endothelium and it is widely acknowledged that numerous chronic inflammation pathways, especially the ...

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

Photochemistry and Photobiology, EarlyView.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

Electromagnetic Quasinormal Modes: A Foundational Framework for Describing Fano Resonances of Extinction Spectra

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
An ab initio electromagnetic framework links quasinormal modes to Fano resonances in extinction spectra. Analytical expressions for the Fano asymmetry and intensity parameters are derived from overlap integrals, enabling rapid spectral reconstruction and physical interpretation.

Interference‐Induced Cavity Resonances and Imaginary Rabi Splitting

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Coupling of a two‐level emitter to (a, b) a single‐mode resonance with a Lorentzian spectral density, and (c, d) a two‐mode cavity with a more complex spectral density. This work reveals a new polaritonic regime beyond the single‐mode description, emerging from emitter interaction with the interference‐induced resonance associated with the Fano ...
