Silver-enhanced lateral flow immunoassay for detection of microcystin-LR in drinking water

نویسندگان

چکیده

An immunochromatographic test system based on the indirect competitive format has been developed for rapid control of cyanotoxin microcystin-LR (MC-LR) in drinking water. To increase assay sensitivity, a hydroquinone-based reduction silver ions surface gold nanoparticles as part immune complexes formed membrane carried out. This stage allows enhancement colouration strip zones. The is characterised by an instrumental limit detection 0.05 ng/mL, cut-off 0.5 and working range detectable concentrations 0.08–0.42 ng/mL. duration was 17 min. applicability MC-LR water demonstrated. recoveries vary from 90% to 120%.

Determination of microcystin-LR in drinking water using UPLC tandem mass spectrometry-matrix effects and measurement.

A simple detection method using ultra-performance liquid chromatography electrospray ionisation tandem mass spectrometry (UPLC-ESI-MS-MS) coupled with the sample dilution method for determining trace microcystin-LR (MC-LR) in drinking water is presented. The limit of detection (LOD) was 0.04 µg/L and the limit of quantitation (LOQ) was 0.1 µg/L. Water matrix effects of ionic strength, dissolved...

Removal of microcystin-LR from drinking water using a bamboo-based charcoal adsorbent modified with chitosan.

A new kind of low-cost syntactic adsorbent from bamboo charcoal and chitosan was developed for the removal of microcystin-LR from drinking water. Removal efficiency was higher for the syntactic adsorbent when the amount of bamboo charcoal was increased. The optimum dose ratio of bamboo charcoal to chitosan was 6:4, and the optimum amount was 15 mg/L; equilibrium time was 6 hr. The adsorption is...

[Microcystin-LR in surface water of Ponjavica River].

BACKGROUND/AIM Cyanobacterial toxins befall a group of various compounds according to chemical structure and health effects on people and animals. The most significant in this large group of compounds are microcystins. Their presence in water used for human consumption causes serious health problems, liver beeing the target organ. Microcystins are spread all over the world. Waterblooms of cyano...
