Advanced Functional Materials, EarlyView.Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Plasmonics in Biology and Plasmon-Controlled Fluorescence [PDF]
Plasmonics, 2006 Fluorescence technology is fully entrenched in all aspects of biological research. To a significant extent, future advances in biology and medicine depend on the advances in the capabilities of fluorescence measurements. As examples, the sensitivity of many clinical assays is limited by sample autofluorescence, single-molecule detection is limited by ...

Advanced Functional Materials, EarlyView.Plasmonic hybridization enables control of light emission in 2D van der Waals heterojunctions. By stacking multilayer GaSe and monolayer MoS2 on a silver film, light emission is enhanced at the edges due to plasmonic effects. In the center, where these effects are absent, charge transfer led to reduced light emission.

Superluminal propagation of surface plasmon polaritons via hybrid chiral quantum dots system
New Journal of PhysicsWe present a novel methodology for enhancing superluminal surface plasmon polaritons (SPPs) propagations within a hybrid nanostructure configuration consisting of gold (Au) metal and chiral quantum dots (CQDs) medium.

Propagation of surface plasmons on plasmonic Bragg gratings [PDF]
Journal of Applied Physics, 2019 We use coupled-mode theory to describe the scattering of a surface-plasmon polariton (SPP) from a square-wave grating (Bragg grating) of finite extension written on the surface of either a metal-dielectric interface or a dielectric-dielectric interface covered with a patterned graphene sheet.

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies
Advanced Functional Materials, EarlyView.This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

Plasmonic tuning of nano-antennas for super-gain light amplification
JPhys PhotonicsNanoscale conductive materials are often used for inducing localized free electron oscillations known as plasmons . This is due to their high electronic excitability under optical irradiation owing to their super-small volume.
