Metal-Enhanced Fluorescence of Silver Island Associated with Silver Nanoparticle

The coupling plasmon of a hybrid nanostructure, silver island (SI) associated with silver nanoparticle (SNP), on metal-enhanced fluorescence (MEF) was studied theoretically. We used the multiple multipole method to analyze the plasmon-mediated enhancement factor on the fluorescence of a molecule immobilized on SNP and located in the gap zone between SI and SNP; herein, the SI was modeled as an ...

Silver Nanoparticle Monolayers for Plasmonics and Surface-Enhanced Raman Spectroscopy

Metal-enhanced fluorescence from silver nanoparticle-deposited polycarbonate substrates{

Silver nanoparticles were deposited onto polycarbonate (PC) films by employing sequential surface modification methods. In the first step, PC films were etched either by exposure to ultra-violet radiation or by etching with sodium hydroxide at 70 uC, which resulted in the formation of a mixture of hydroxyl and carboxyl groups on the surface of the films. Next, the PC films were silanized with 3...

Characterization and optimization of gold nanoparticle-based silver-enhanced immunoassays.

Silver-enhanced nanoparticle-labeled immunoassays provide a simple, low-cost, and effective way of detecting antigens in dilute solutions. The physical mechanisms behind their operation, however, have not been fully investigated. We present a semiquantitative approach for optimizing sandwich nanoparticle immunoassays using an adsorption-controlled kinetic model. Primary antibodies were immobili...

Biomolecules Detection Using a Silver-Enhanced Gold Nanoparticle-Based Biochip

Silver-enhanced labeling method has been employed in immunochromatographic assays for improving the sensitivity of detecting pathogens. In this paper, we apply the silver enhancement technique for biomolecular signal amplification in a gold nanoparticle-based conductimetric biochip. We show that the response of the silver-enhanced biochip comprises two distinct regions namely: (a) a sub-thresho...
