Gold nanoparticle-based lateral flow biosensor for rapid visual detection of Leishmania-specific DNA amplification products

Journal of Microbiological Methods, 2016
Leishmaniasis is a disease, caused by Leishmania parasites, which infect humans and animals, posing a major social and economic burden worldwide. The need for accurate and sensitive disease diagnosis led to the widespread adoption of PCR amplification. Detection of the amplification products (i.e.

Dry-reagent gold nanoparticle-based lateral flow biosensor for the simultaneous detection of Vibrio cholerae serogroups O1 and O139

Journal of Microbiological Methods, 2011
Cholera is a communicable disease caused by consumption of contaminated food and water. This potentially fatal intestinal infection is characterised by profuse secretion of rice watery stool that can rapidly lead to severe dehydration and shock, thus requiring treatment to be given immediately.

Visual and multiplex detection of nucleic acid sequence by multiple cross displacement amplification coupled with gold nanoparticle-based lateral flow biosensor

Sensors and Actuators B: Chemical, 2017
Abstract Here, we reported on the establishment of a nearly instrument free, simple and rapid molecular technique, which incorporated multiple cross displacement amplification coupled with lateral flow biosensor (MCDA-LFB) for the visual, sensitive and specific detection of nucleic acid sequence.

The colloidal gold nanoparticle based-lateral flow immunoassay for fast and simple detection of plant-derived doping agent, higenamine.

Drug Testing and Analysis, 2020
Higenamine (HM), an alkaloid found in various plant species, is obtained when norcoclaurine synthase selectively condenses dopamine and 4-hydroxyphenylacetaldehyde to give (S)-higenamine ((S)-HM).

Gold nanoparticle based immunochromatographic biosensor for rapid diagnosis of Mycobacterium avium subspecies paratuberculosis infection using recombinant protein.

Journal of Microbiological Methods, 2020
Highly infectious and obvious withstand ability of Mycobacterium avium subspecies paratuberculosis (MAP) to environment as well as lack of on-site field diagnostic methods notably hampers the Paratuberculosis (PTB) control.

A Lateral Flow Biosensor Based on Isothermal Amplification for Visual Identification of Species and Sex from Bloodstain.

Analytical Chemistry
The prompt species identification from biological samples at a crime scene can rapidly filter out truly valuable biometric information for subsequent personal identification. Meanwhile, early sex determination can assist in narrowing the pool of suspects.

Biosensor‐based multiple cross displacement amplification platform for visual and rapid identification of hepatitis C virus

Journal of Medical Virology
Hepatitis C remains a global health problem, especially in poverty‐stricken areas. A rapid and sensitive point‐of‐care (POC) diagnostic tool is critical for the early detection and timely treatment of hepatitis C virus (HCV) infection.
