Biosensors and Bioelectronics, 2011
In this article, we describe an ultrasensitive nucleic acid biosensor (NAB) based on horseradish peroxidase (HRP)-gold nanoparticle (Au-NP) dual labels and lateral flow strip biosensor (LFSB). The results presented here expand on prior work (Mao et al., 2009a) by optimizing the preparation of HRP-Au-NP-DNA conjugates.

Paper-Based Biosensors with Lateral/Vertical Flow Assay
2020The lateral flow assay (LFA), which is a simple paper-based device for the detection and analysis of disease, is now the most predominant diagnostic platform in point-of-care (POC) markets [1, 2, 3, 4]. This market-dominating power stems from the unique characteristics of the LFA: low cost, portability, versatility, easy use, free of other instruments,

A Lateral Flow Biosensor for the Detection of Single Nucleotide Polymorphisms
2017A lateral flow biosensor (LFB) is introduced for the detection of single nucleotide polymorphisms (SNPs). The assay is composed of two steps: circular strand displacement reaction and lateral flow biosensor detection. In step 1, the nucleotide at SNP site is recognized by T4 DNA ligase and the signal is amplified by strand displacement DNA polymerase ...

Nanolabels for biosensors based on lateral flow immunoassays
Analytica Chimica ActaThe 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

Carbon nanotube-based lateral flow biosensor for sensitive and rapid detection of DNA sequence
Biosensors and Bioelectronics, 2015In this article, we describe a carbon nanotube (CNT)-based lateral flow biosensor (LFB) for rapid and sensitive detection of DNA sequence. Amine-modified DNA detection probe was covalently immobilized on the shortened multi-walled carbon nanotubes (MWCNTs) via diimide-activated amidation between the carboxyl groups on the CNT surface and amine groups ...

Biosensors and lateral flow immunoassays: Current state and future prospects
Clinica Chimica ActaThe advent of paper-based biosensors represents a novel paradigm in point-of-care (POC) diagnostics, emerging as versatile tools. However, the broad term "biosensors" can be misleading, encompassing a range of techniques such as dipstick assays, electrochemical, microfluidics and immunoassay-based biosensors (including lateral flow (LFA), vertical flow
