Recent Advances in Nanoparticles-based Lateral Flow Biosensors
Lateral flow biosensors (LFBs) provide advantages in low cost, simplicity, rapidity, stability and portability, thus making LFBs popular in biomedical, agriculture, food and environmental sciences. This article reviews recent advances of LFBs for bioassays, including the investigation of the improvements achieved by signal-amplification strategies, the application of new nanoparticle labels, no...
متن کاملNanoparticle-based photoacoustic analysis for highly sensitive lateral flow assays.
This paper demonstrates a photoacoustics-based lateral flow test that takes advantage of the strong interaction of light and gold nanoparticles to quantitatively detect a disease biomarker. For a commercially available lateral flow test strip, the photoacoustic analysis improved the detection limit by two orders of magnitude compared to colorimetric measurements.
متن کاملColorimetric biosensors based on DNA-nanoparticle conjugates.
In this review, we present an overview of the technologies in colorimetric biosensors based on DNA-nanoparticle conjugates. Two types of DNA-nanoparticles aggregation assays are summarized. One of the methods relies on cross-linking of the gold nanoparticle (GNP) by hybridization. The crosslinking system was used not only to detect target DNA sequences, but also to detect metal ions or small mo...
متن کاملNanoparticle embedded enzymes for improved lateral flow sensors.
In this study, combining the nanoparticle embedded sensors with lateral flow assays, a novel strategy for ensuring the quality of signalling in lateral flow assays (LFAs) was developed. A LFA for reactive oxygen species (ROS) is reported that is based on horse radish peroxidase (HRP) which is co-entrapped with Texas Red dextran inside porous polyacrylamide nanoparticles. In this system, enzymes...
