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

Nanoparticle-based lateral flow biosensors [PDF]
Biosensors and Bioelectronics, 2015 Lateral flow biosensors (LFBs) are paper-based devices which permit the performance of low-cost and fast diagnostics with good robustness, specificity, sensitivity and low limits of detection. The use of nanoparticles (NPs) as labels play an important role in the design and fabrication of a lateral flow strip (LFS).

An enzyme-amplified lateral flow strip biosensor for visual detection of MicroRNA-224
Talanta, 2016An enzyme-based dual-labeled nanoprobe is designed to fabricate a sensitive enzyme-amplified lateral flow biosensor for visual detection of mircoRNA-224 (miRNA-224). The recognition DNA probe (detection probe) and signal amplification enzyme (Horseradish peroxidase, HRP) are immobilized on gold nanoparticle (GNPs) surface, simultaneously.

Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy, 2020
Vaspin is a protein present in human serum that can cause type-2 diabetes, obesity, and other cardiovascular diseases. We report fluorescent upconverting nanoparticles (UCNPs)-based lateral flow biosensor for ultrasensitive detection of Vaspin. A pair (primary and secondary) of cognate aptamers was used that has duo binding with Vaspin.
