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.

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

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

Current Topics in Medicinal Chemistry, 2019
Pathogenic bacteria constitute one of the most serious threats to human health. This has led to the development of technologies for the rapid detection of bacteria. Bio-nanogold-based lateral flow biosensors (LFBs) are a promising assay due to their low limit of detection, high sensitivity, good selectivity, robustness, low cost, and quick assay ...
