By a News Reporter-Staff News Editor at Science Letter -- New research on Pesticides is the subject of a report. According to news originating from Chandigarh, India, by NewsRx correspondents, research stated, "Plasmon enhanced fluorescence immunoassay (PEFI) format has been reported in developing a sensitive heterogeneous fluoroimmunoassay for monitoring the phenylurea herbicide diuron. Computer-assisted molecular modeling was carried out to study the conformational and electrostatic effects of synthesized hapten for producing highly specific egg yolk antibody against a phenyl urea herbicide diuron."
Our news journalists obtained a quote from the research from the Institute of Microbial Technology, "The generated antibodies were labeled with fluorescein isothiocyanate at different molar ratios and used as tracer in the developed fluorescence based immunoassay. The sensitivity of the assay format was enhanced by using silver nanoparticles tagged with bovine serum albumin as a new blocking reagent in the developed PEFI format. Enhancer treatment on the developed immunoassay showed a significant improvement of fluorescence signal intensity with approximately 10 fold increase in assay sensitivity. The immunoassay has a detection limit of 0.01 ng mL(-1) with good signal precision (~2%) in the optimum working concentration range between 1 pg mL(-1) to 10 ?g mL(-1) of diuron."
According to the news editors, the research concluded: "These findings facilitate high throughput fluorescence-based processes that could be useful in biology, drug discovery and compound screening applications."
