Controlling plasmon-exciton interactions through photothermal reshaping

Opto-Electronic Advances, 2020
We investigated the plasmon-exciton interactions in an individual gold nanorod (GNR) with monolayer MoS2 at room temperature with the single-particle spectroscopy technique.

Electrical Control of Plasmon Resonance with Graphene [PDF]

, 2012
Surface plasmon, with its unique capability to concentrate light into sub-wavelength volume, has enabled great advances in photon science, ranging from nano-antenna and single-molecule Raman scattering to plasmonic waveguide and metamaterials.

Strong exciton-plasmon coupling in semiconducting carbon nanotubes [PDF]

, 2009
We study theoretically the interactions of excitonic states with surface electromagnetic modes of small-diameter (~1 nm) semiconducting single-walled carbon nanotubes. We show that these interactions can result in strong exciton-surface-plasmon coupling.

Discovery of (phenylureido)piperidinyl benzamides as prospective inhibitors of bacterial autolysin E from Staphylococcus aureus

Journal of Enzyme Inhibition and Medicinal Chemistry, 2018
Autolysin E (AtlE) is a cell wall degrading enzyme that catalyzes the hydrolysis of the β-1,4-glycosidic bond between the N-acetylglucosamine and N-acetylmuramic acid units of the bacterial peptidoglycan.

Using surface plasmonics to turn on fullerene's dark excitons [PDF]

, 2014
Using our recently proposed Bethe-Salpeter $G_0W_0$ formulation, we explore the optical absorption spectra of fullerene (C$_{60}$) near coinage metal surfaces (Cu, Ag, and Au). We pay special attention to how the surface plasmon $\omega_S$ influences the

Ellipsometric surface plasmon resonance

Journal of Biomedical Optics, 2009
We develop a new multifunctional optical biochip system that integrates an ellipsometer with a surface plasmon resonance (SPR) feature. This newly developed biochip biosensor, which we call ESPR for an ellipsometric SPR, provides us with a system to retrieve detailed information such as the optical properties of immobilized biomolecular monolayers ...

Au-Ag Gradient Alloy Nanoparticles with Extended Surface Plasmon Resonance Wavelength: Synthesis via Microreaction

Nano Biomedicine and Engineering, 2011
Au-Ag gradient alloy nanoparticles were directly synthesized in a microreaction system with their surface plasmon resonance been facilely adjusted. The surface plasmon resonance wavelength was red-shifted through increasing the raw ratio of Au3+:Ag ...

Microscopic theory of surface-enhanced Raman scattering in noble-metal nanoparticles [PDF]

, 2006
We present a microscopic model for surface-enhanced Raman scattering (SERS) from molecules adsorbed on small noble-metal nanoparticles. In the absence of direct overlap of molecular orbitals and electronic states in the metal, the main enhancement source
