A dual gold nanoparticle conjugate-based lateral flow assay (LFA) method for the analysis of troponin I.

Development of a Lateral Flow Immunoassay Using Recombinant Dense Granular Antigen (GRA) 7 to Detect Anti-Toxoplasma gondii IgG Antibodies

Toxoplasma gondii is an intracellular protozoan parasite that causes toxoplasmosis and is of medical importance in pregnant women and immunosuppressed patients. In recent years, many methods have been developed for the detection of infection caused by this parasite; however, most of the developed methods are not adequately sensitive. The dense granular antigen (GRA) ...

ENHANCED PERFORMANCE OF A LATERAL FLOW ASSAY Use of a novel conjugate blocking technology to improve performance of a gold nanoparticle-based lateral flow assay

A lateral flow paper microarray for rapid allergy point of care diagnostics.

There is a growing need for multiplexed specific IgE tests that can accurately evaluate patient sensitization profiles. However, currently available commercial tests are either single/low-plexed or require sophisticated instrumentation at considerable cost per assay. Here, we present a novel convenient lateral flow microarray-based device that employs a novel dual labelled gold nanoparticle-str...

Apolipoprotein E genotyping using PCR-GoldMag lateral flow assay and its clinical applications

A polymerase chain reaction-gold magnetic nanoparticles lateral flow assay (PCR-GoldMag LFA) has been developed via integrating multiplex amplification refractory mutation system PCR (multi‑ARMS‑PCR) with GoldMag‑based LFA for the visual detection of single‑nucleotide polymorphisms (SNPs). This assay was applied to genotype Apolipoprotein E (ApoE). ApoE genotyping is important due to the predic...

Gold magnetic nanoparticle conjugate-based lateral flow assay for the detection of IgM class antibodies related to TORCH infections.

In this study, a lateral flow immunochromatographic assay (LFIA) system for the detection of immunoglobulin M (IgM) antibodies, related to TORCH [(T)oxoplasmosis, (O)ther agents, (R)ubella (also known as German Measles), (C)ytomegalovirus, and (H)erpes simplex virus infections], based on gold magnetic nanoparticles, was established. Following modification with poly(methacrylic acid), the gold m...
