Heavy Metal Ion Sensing By Surface Plasmon Resonance on Gold

Chem. Soc. Rev. 35, 209–217. doi: 10.1039/b514191e. Surface plasmon resonance of gold nanoparticles assemblies at liquid | liquid interfaces In the case of gold nanorod the plasmon resonance splits into two modes: one longitudinal mode parallel to the long axis of the rod and a transverse mode perpendicular to the first. In this work we use photoacoustic (PA) technique to study the shape dependence of surface plasmon resonance of gold nanoparticles (dots and rods) in addition to their dependence on the aspect ratio in the case of The presence of longitudinal surface plasmon resonance (LSPR) provides GNRs with richer optical properties, which lead to local field, Raman, and fluorescence enhancement. When QDs bind with GNRs, the fluorescence intensity of the QDs is enhanced by the near-fired plasmonic resonance from the GNR surface and their photoluminescence (PL) emission increases [20-23] .

Plasmon resonance of gold nanoparticles

ACS Applied Materials & Interfaces 2018, 10 (47) , 40958-40965. Gold nanoparticles (AuNPs) are attracting a great deal of attention due to their optical properties related to surface plasmon resonance (SPR), which depends, not only on the metal itself and on its environment, but also on the size and shape of the particle [5,6]. SPR is related to optically induced collective excitations of conduction electrons. 2016-05-15 · Localised surface plasmon resonance (LSPR) of gold nanoparticles (AuNPs) has been exploited for two decades in analytical science and has proven to be a powerful tool for the detection of various kinds of substances including small molecules, ions, macro biomolecules and microbes.

In fact, plasmons are highly responsive to a multitude of factors, either intrinsic to the Au … 2013-04-01 This structural control provides a method for systematically shifting the surface plasmon resonance (SPR) of the particles, based on the decrease in dipolar coupling with increased interparticle distance. Through choice of dendrimer generation, we were able to tune interparticle spacing over a 2.1 nm range, resulting in an 84 nm shift in the SPR. Gold nanoparticles (Au NPs) with an average size of about 10 nm were deposited in situ into the TiO 2 bi-layer structure.
