Lateral Flow Immunoassays

2018
The lateral flow (immuno)assay is a relatively old diagnostic platform that was developed in the 1980s. Over the almost 30 years since, a very diverse panel of lateral flow immunoassays has been developed and marketed. At the moment the platform is being transformed into a modern diagnostic tool that can be integrated with nowadays technologies, such ...

Multiplexed detection of biomarkers in lateral-flow immunoassays

The Analyst, 2020
Multiplexed detection of biomarkers, i.e. , simultaneous detection of multiple biomarkers in a single assay, can enhance diagnostic precision, improve diagnostic efficiency, reduce diagnostic cost, and alleviate pain of patients.

Lateral-flow immunoassays for mycotoxins and phycotoxins: a review

Analytical and Bioanalytical Chemistry, 2012
Natural toxin (for example mycotoxin and phycotoxin) contamination of food is of safety and economic concern, so much effort is devoted to the development of screening methods which enable the toxins to be continuously and widely monitored in food and feed.

Multiplex Lateral Flow Immunoassay for Mycotoxin Determination

Analytical Chemistry, 2014
A new lateral flow immunoassay (LFA) is proposed for qualitative and/or semiquantitative determination of aflatoxin B1 (AFB1), zearalenone (ZEA), deoxynivalenol (DON), and their analogues (AFs, ZEAs, DONs) in cereal samples. Each of the mycotoxin specific antibody was class specific and there was no cross reactivity to other groups of compounds.

Nanocellulose aerogel inserts for quantitative lateral flow immunoassays

Biosensors and Bioelectronics, 2021
The Lateral Flow Immuno Assay (LFIA) is a well-established technique that provides immediate results without high-cost laboratory equipment and technical skills from the users. However, conventional colorimetric LFIA strips suffer from high limits of detection, mainly due to the analysis of a limited sample volume, short reaction time between the ...

Replacing antibodies with aptamers in lateral flow immunoassay

Biosensors and Bioelectronics, 2015
Aptamers have been identified against various targets as a type of chemical or nucleic acid ligand by systematic evolution of ligands by exponential enrichment (SELEX) with high sensitivity and specificity. Aptamers show remarkable advantages over antibodies due to the nucleic acid nature and target-induced structure-switching properties and are widely

Lateral flow immunoassay for progesterone detection

Moscow University Chemistry Bulletin, 2012
A new express method based on lateral flow immunoassay (LFIA) for progesterone detection was developed. To increase the assay sensitivity an enzyme label (horse-radish peroxidase) was used instead of colloidal gold. An optimal assay format was chosen and the influence of a range of buffer supplements (detergents, proteins and sucrose) was investigated ...

Nanolabels for biosensors based on lateral flow immunoassays

Analytica Chimica Acta
The COVID-19 outbreak was an important turning point in the development of a new generation of biosensing technologies. The synergistic combination of an immunochromatographic test (lateral flow immunoassays, LFIA) and signal transducers provides enhanced sensitivity and the ability to quantify in the rapid tests. This is possible due to the variety of

Laser-fabricated gold nanoparticles for lateral flow immunoassays

Colloids and Surfaces B: Biointerfaces, 2017
Gold nanoparticles fabricated by pulsed laser ablation are an attractive alternative over those made by chemical reduction, as they offer a more reactive, chemically-bare surface. In this manuscript, we investigate the interactions of these nanoparticles with different classes of antibodies and quantify surface coverage via a fluorescence-based ...
