Advances in Localized Surface Plasmon Resonance Spectroscopy Biosensing

Nanomedicine, 2011
In recent years, localized surface plasmon resonance (LSPR) spectroscopy advancements have made it a sensitive, flexible tool for probing biological interactions. Here, we describe the basic principles of this nanoparticle-based sensing technique, the ways nanoparticles can be tailored to optimize sensing, and examples of novel LSPR spectroscopy ...

Localized Surface Plasmon Resonances of Anisotropic Semiconductor Nanocrystals

Journal of the American Chemical Society, 2011
We demonstrate that anisotropic semiconductor nanocrystals display localized surface plasmon resonances that are dependent on the nanocrystal shape and cover a broad spectral region in the near-IR wavelengths. In-plane and out-of-plane dipolar resonances were observed for colloidal dispersions of Cu(2-x)S nanodisks, and the wavelengths of these ...

Sensitive Localized Surface Plasmon Resonance Multiplexing Protocols

Analytical Chemistry, 2012
Herein are reported two new protocols to obtain different zones of localized surface plasmon resonance (LSPR) gold nanostructures on single glass substrate by using a vacuum evaporation technique followed by a high-temperature annealing (550 °C). The thickness of the gold film, considered as the essential parameter to determine specific LSPR properties,

Determination of DNA based on localized surface plasmon resonance

Colloids and Surfaces B: Biointerfaces, 2010
A resonance light scattering (RLS) spectrometry for determining DNA based on localized surface plasmon resonance (LSPR) of gold nanorods was developed. The fabrication and characterization of the biosensor utilized gold nanorods as the optical transducer was described. The DNA was determined based on the binding of DNA to gold nanorods by electrostatic

Potential-Scanning Localized Surface Plasmon Resonance Sensor

ACS Nano, 2015
Localized surface plasmon resonance (LSPR) sensors based on plasmonic nanoparticles attract much attention recently. Here we propose a new class of LSPR sensor, that is, a potential-scanning LSPR sensor, in which electron density of the plasmonic nanoparticles is controlled by potential scanning.

Analysis of immunoreaction with localized surface plasmon resonance biosensor

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2010
The localized surface plasmon resonance (LSPR)-based optical biosensor was used as a potential tool for label-free detection of immunoreaction. The glass substrate covered with the self-assembled monolayer (SAM) of gold colloids was used widely in the sensors.

Localized Surface Plasmon Resonances

2017
Surface plasmon polaritons are propagating energy waves at a plane metallic–dielectric interface. Metallic nanoparticles supply an effective restoring force to drive electrons in an oscillating electromagnetic field. A specific resonance condition leads to a field amplification localized in the near zone inside and outside the particle.
