چکیده

A novel biosensing strategy has been developed for sensitive detection of β-amyloid 1-42 (Aβ(1-42)) down to the ng mL(-1) level in both aqueous solution and diluted human plasma, which is based on measuring changes in resonance light scattering of streptavidin functionalized gold nanoparticles as a function of the concentration of Aβ(1-42) with a conventional spectrofluorometer.

Microarray-based resonance light scattering assay for detecting DNA methylation and human DNA methyltransferase simultaneously with high sensitivity.

A microarray-based resonance light scattering assay, with the combination of methylation-sensitive endonuclease and gold nanoparticle (GNP) probes, has been proposed to sensitively distinguish the DNA methylation level as low as 0.01% (10 pM methylated DNA in 100 nM total DNA) and detect human DNA methyltransferase 1 (Dnmt1) down to 0.1 U mL(-1).

Homogeneous detection of nucleic acids based upon the light scattering properties of silver-coated nanoparticle probes.

Herein we report the development of a simple, rapid, homogeneous, and sensitive detection system for DNA based on the scattering properties of silver-amplified gold nanoparticle probes. The assay uses DNA-functionalized magnetic particle probes that act as scavengers for target DNA, which can be collected via a magnetic field. Once the DNA targets are isolated from the initial sample, they are ...

Gold nanoparticle based dot-blot immunoassay for sensitively detecting Alzheimer's disease related β-amyloid peptide.

A simple, sensitive gold nanoparticle (GNP)-based dot-blot immunoassay has been developed for detecting Alzheimer's disease related β-amyloid peptide 1-42 (Aβ(1-42)) down to a 50 pg mL(-1) level in aqueous solution. Practical samples (cerebrospinal fluid (CSF), cell culturing mediums and cell lysates) have been used to demonstrate the ability of the assay.
