Dual Enhancement with a Nanoparticle-Based Lateral Flow Biosensor for the Determination of DNA
Analytical Letters, 2015ABSTRACTAn attractive methodology for the one-step signal amplification in a gold nanoparticle-based lateral flow biosensor was successfully applied for nucleic acid determination. This relatively new methodology, namely the “dual gold signal enhancement method” utilizes two gold nanoparticle-antibody conjugates, responsible for both the ...

Disposable Nucleic Acid Biosensors Based on Gold Nanoparticle Probes and Lateral Flow Strip
Analytical Chemistry, 2009In this article, we describe a disposable nucleic acid biosensor (DNAB) for low-cost and sensitive detection of nucleic acid samples in 15 min. Combining the unique optical properties of gold nanoparticles (Au-NP) and the high efficiency of chromatographic separation, sandwich-type DNA hybridization reactions were realized on the lateral flow strips ...

The use of potential mutagenic nitrofuran antibiotic in food animal production has been banned world-wide. Common methods for nitrofuran detection involve complex extraction procedures. In the present study, magnetic beads functionalized with antibody against nitrofuran derivative were used as both the extraction and color developing media in lateral ...

A lateral flow biosensor for detection of single nucleotide polymorphism based on circular strand displacement reaction (CSDPR) has been developed. Taking advantage of high fidelity of T4 DNA ligase, signal amplification by CSDPR, and the optical properties of gold nanoparticles, this assay has reached a detection limit of 0.01 fM.

Towards All-Printed Lateral Flow Biosensors
2019Many devices in our day-to-day lives incorporate lateral flow biosensors, for example, home pregnancy test kits. These tests allow users to obtain results within 30 minutes by simply applying a few droplets of urine onto a test strip. However, these biosensors are largely manufactured using manual processes: workers cut strips (also called substrates ...
