Visual detection of microRNA with lateral flow nucleic acid biosensor [PDF]

open access: yesBiosensors and Bioelectronics, 2014
We report a DNA-gold nanoparticle (DNA-GNP) based lateral flow nucleic acid biosensor for visual detection of microRNA (miRNA)-215 in aqueous solutions and biological samples with low-cost and short analysis time. Sandwich-type hybridization reactions among GNP-labeled DNA probe, miRNA-215 and biotin-modified DNA probes were performed on the lateral ...

Aptamer-based lateral flow assay on-site biosensors

Biosensors and Bioelectronics, 2021
The lateral flow assay (LFA) is a widely used paper-based on-site biosensor that can detect target analytes and obtain test results in several minutes. Generally, antibodies are utilized as the biorecognition molecules in the LFA. However, antibodies selected using an in vivo process not only may risk killing the animal hosts and causing errors between

In Planta Microsphere-Based Lateral Flow Leaf Biosensor in Maize

open access: yesSLAS Technology, 2015
Low-cost and quick detection of biotic stresses is critically important for protection of staple food crops such as maize in smallholder farms in developing countries, where access to improved seed varieties, fertilizers, and pesticides is limited due to financial and geographical reasons.
