A smartphone-based dual-modal lateral flow immunochromatographic assay for multiplex detection of illegal stimulant laxatives in slimming foods.

Stimulant laxatives (especially bisacodyl and sodium picosulfate) are frequently found to be adulterated into slimming foods, causing health-threatening effects to consumers. Sensitive, accurate, easy-to-operate and portable multiplex analytical techniques are still desired for the rapid screening of stimulant laxatives in slimming foods. In this work, a highly sensitive dual-modal colorimetric/photothermal lateral flow immunochromatographic assay (LFIA) was established based on facilely prepared concentrated gold nanoparticles (cAuNPs).

Human strongyloidiasis is an important intestinal parasitic disease that affects public health globally and is transmitted through contact with infective larvae on contaminated soil. Immunocompromised hosts can experience hyperinfection, which can lead to fatal systemic strongyloidiasis. Here, an innovative point-of-care (POC) test kit, the strongyloidiasis immunochromatographic blood test (the NIE-SsIR whole-blood ICT) kit is described.

College of Life Sciences, Northwest University, Xi'an, 710069, China. Electronic address:
Straightforward genotyping can provide timely diagnostic information for diseases prevention and treatment. Taking advantages of speediness and convenience, although numerous genotyping strategies combined loop-mediated isothermal amplification (LAMP) and lateral flow have been reported to satisfy the demand of point-of-care test, the false positive result caused by aerosol and primer dimer as an innate conflict seriously limits their practical application. In this study, both aerosol and primer dimer as extrinsic and intrinsic inducements respectively are first broken through at one stroke based on an integrated immunochromatographic biosensor.

In 2009, severe fever with thrombocytopenia syndrome virus (SFTSV), also known as the (DBV), was first discovered in Henan, China. It is a tick-borne zoonotic virus with a fatality rate ranging from 6% to 30%. Currently, we lack safe and effective vaccines or antiviral drugs to treat SFTSV infection.

A specific anti-triadimefon monoclonal antibody (mAb) was conjugated with TRFM to fabricate LFIA test strips. A time-resolved fluorometer as an LFIA reader was applied to obtain quantitative results and assess risk ranges for the LFIA test strips.
