Quantitative and rapid detection of spinosad and spinetoram by a gold nanoparticle-based immunostrip

Abstract

Spinosad (SPI) and spinetoram (Et-SPI) are currently one of the most popular new insecticides because of their high efficiency and low toxicity. However, excessive residues in food still pose a...

Rapid and sensitive detection of chlordimeform in cucumber and tomato samples using an immunochromatographic assay

“…Optimal hybridoma cells that secreted anti-CDM mAbs were collected and injected intraperitoneally into two female mice, and the ascites fluid was purified to obtain anti-CDM mAbs. 30 All animal experiments were performed in accordance with the Guidelines for Care and Use of Laboratory Animals of Jiangnan University, and approved by the ethics Committee on Animal Welfare of Jiangnan University (Wuxi, China).…”

Development of a gold nanoparticle-based lateral-flow strip for the detection of cannabidiol in functional beverages

“…Similar to ic-ELISA (Lei et al , 2022), 34 the ICA test strip is based on the competitive reaction of small molecule antigens. Fig.…”

Development of a colloidal gold strip assay for the detection of total homocysteine in serum samples

“…Colloidal gold (CG) nanoparticles (30 nm) were synthesized using the citric acid reduction method, as previously reported. 28 Briefly, 100 mL of 0.01% (w/v) chlorauric acid solution was added to a clean flask and heated to boiling with magnetic stirring and then 5 mL of 1% (w/v) trisodium citrate solution was quickly added. The color of the solution changed from colorless to black and then quickly to a bright red wine color.…”
