Analytical and Bioanalytical Chemistry, 2016
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 ...

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 ...

Double-Enhanced Photothermal Lateral Flow Biosensor Based on Dual Gold Nanoparticle Conjugates
ACS SensorsBacterial toxins emerge as the primary triggers of foodborne illnesses, posing a significant threat to human health. To ensure food safety, it is imperative to implement point-of-care testing methods. Lateral flow biosensors (LFBs) based on gold nanoparticles (GNPs) have been commonly used for rapid detection, but their applicationis limited by low ...

Development of molecular lateral flow biosensors for non-covered medical needs
2023La pandèmia actual de SARS-CoV-2 ha ressaltat la importància de poder desenvolupar, produir i desplegar ràpidament proves de diagnòstic per a malalties infeccioses emergents, ja que el SARS-CoV-2 no serà l'última amenaça. A més, la prevalença creixent de la resistència als antimicrobians s'ha convertit en una pandèmia silenciosa que ja s'està cobrant ...
