Carboxyl retained hapten of quinclorac produces highly sensitive antibody and immunochromatographic assay

Cobalt phthalocyanine (CoPc) anchored on Ti3C2 MXene nanosheets for highly efficient selective catalytic oxidation

“…[23][24][25] The attempt to produce quinclorac with molecularly dispersed metal phthalocyanine catalysts in the presence of molecular oxygen has never been reported, to the best of our knowledge. [26][27][28][29] In this work, we report the realization of quinclorac synthesis enabled by anchoring CoPc onto Ti 3 C 2 MXene nanosheets for the design of a new kind of CoPc/Ti 3 C 2 -Mn(OAc) 2 -HBr (CoPc/ Ti 3 C 2 -4.5%-Mn-Br) system with oxygen as the oxidant. This enables CoPc/Ti 3 C 2 -4.5%-Mn-Br to exhibit a high catalytic activity for the production of high value-added quinclorac with a yield of 87.5%, which is even 2.46-fold higher than that of the CoPc-Mn-Br system.…”

A Rapid and Sensitive Gold Nanoparticle-Based Lateral Flow Immunoassay for Chlorantraniliprole in Agricultural and Environmental Samples

“…Currently, the detection methods for CAP include gas chromatography-mass spectrometry (GC−MS) [6][7][8][9] and liquid chromatography-tandem mass spectrometry (LC−MS/ MS) [10][11][12][13][14]. The reported methods are sensitive and exact, but they require costly equipment and time-consuming sample pre-treatment [15].…”

“…Compared with ELISAs, gold nanoparticle-based lateral flow immunoassays (AuNP-LFIAs) possess the advantages of one-step detection and do not require specialized equipment and direct visual readout [17]. Therefore, they have tremendous potential for on-site rapid testing and have been used to detect various small-molecule pesticides, such as quizalofop-p-ethyl [20], quinclorac [15], and deoxynivalenol [21]. However, no AuNP-LFIA-based monoclonal antibody has been reported for CAP.…”
