Journal ArticleDOI
Extinction coefficient of gold nanoparticles with different sizes and different capping ligands.
TL;DR: A linear relationship between the logarithms of extinction coefficients and core diameters of gold particles was found independent of the capping ligands on the particle surface and the solvents used to dissolve the nanoparticles, and may be used as a calibration curve to determine the concentration or average size of an unknown nanoparticle or nanoparticle-biomolecule conjugate sample.
Journal ArticleDOI
A One-Step Homogeneous Immunoassay for Cancer Biomarker Detection Using Gold Nanoparticle Probes Coupled with Dynamic Light Scattering
Xiong Liu,Qiu Dai,Lauren A. Austin,Janelle L. Coutts,Genevieve Knowles,Jianhua Zou,Hui Chen,Qun Huo +7 more
TL;DR: A one-step homogeneous immunoassay for the detection of a prostate cancer biomarker, free-PSA (prostate specific antigen), was developed using gold nanoparticle probes coupled with dynamic light scattering (DLS) measurements.
Journal ArticleDOI
Gold nanoparticle-enabled biological and chemical detection and analysis
Hilde Jans,Qun Huo +1 more
TL;DR: An overview of the optical properties of AuNPs is presented, followed by a more detailed literature survey, and some technical issues that remain to be solved in order to move the technique forward.
Journal ArticleDOI
Dynamic light scattering as a powerful tool for gold nanoparticle bioconjugation and biomolecular binding studies.
TL;DR: For the first time, DLS is able to directly and quantitatively measure the binding stoichiometry between a protein-conjugated GNP probe and a target analyte protein in solution.
