Distance-Dependent Fluorescence Resonance Energy Transfer Enhancement on Nanoporous Gold

open access: yesNanomaterials, 2021
Fluorescence resonance energy transfers (FRET) between cyan fluorescent protein (CFP) and yellow fluorescent protein (YFP) on nanoporous gold (NPG) are systematically investigated by controlling the distance between NPG and fluorescent proteins with ...

Plasmonics in Biology and Plasmon-Controlled Fluorescence [PDF]

open access: yesPlasmonics, 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 ...

Effect of Glutathione on the Destruction Kinetics of Silver Nanoparticles in Aqueous Solutions: An Optical Study under Neutral and Alkaline Conditions

open access: yesEngineering Proceedings, 2023
The interaction of nanostructured metal particles with the molecular components of biosystems differs significantly from the processes that take place in the presence of ions of the same metals.

Graphene Terahertz Plasmon Oscillators

open access: yes, 2007
In this paper we propose and discuss coherent terahertz sources based on charge density wave (plasmon) amplification in two dimensional graphene. The coupling of the plasmons to interband electron-hole transitions in population inverted graphene layers ...

Dispersion and lineshape of plasmon satellites in one, two and three dimensions

open access: yes, 2016
Using state-of-the-art many-body Green's function calculations based on the "GW plus cumulant" approach, we analyze the properties of plasmon satellites in the electron spectral function resulting from electron-plasmon interactions in one-, two- and ...

Surface Plasmons Excited by X-rays in the Surface Layers of Solids

open access: yesSolids, 2022
The phenomenon of total external reflection of X-rays at a sliding angle of incidence of a beam of incident X-rays is investigated. For metals, a quantitative law of direct dependence of the refractive index decrement on the interplane distance is ...

Nonlinear dynamics of soft boson excitations in hot QCD plasma I: plasmon-plasmon scattering [PDF]

open access: yes, 2002
On the basis of pure gauge sector of Blaizot-Iancu equation, we derive kinetic equation of Boltzmann type, taking into account 2n+2-colorless plasmon decay processes, n=1,2,....
