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 ...

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 ...

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 ...

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 ...

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 ...
