The specific immunochemical detection of 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic acid pesticides by amperometric cholinesterase biosensors

Inhibition-Based Biosensors for the Detection of Environmental Contaminants: Determination of 2,4-Dichlorophenoxyacetic Acid

“…For these reasons a reliable and rapid technique for the determination of 2,4-D in aqueous samples is increasingly necessary. Apart from classic HPLC and GC-MS techniques, several immunosensors recently have been developed for the determination of 2,4-D [30][31][32][33][34][35]. The goal of this work was the development of a biosensor capable not only of detecting a single chemical species, but also of giving a global evaluation of the overall contamination of the sample by 2,4-D and its analogs, which are endowed with the same toxicity.…”

Inhibition‐based biosensors for the detection of environmental contaminants: Determination of 2, 4‐dichlorophenoxyacetic acid

“…For these reasons a reliable and rapid technique for the determination of 2, 4‐D in aqueous samples is increasingly necessary. Apart from classic HPLC and GC‐MS techniques, several immunosensors recently have been developed for the determination of 2, 4‐D [30–35]. The goal of this work was the development of a biosensor capable not only of detecting a single chemical species, but also of giving a global evaluation of the overall contamination of the sample by 2, 4‐D and its analogs, which are endowed with the same toxicity.…”

Determination of pesticides by enzyme immunoassay

“…Capillary electrophoretic immunoassay with electrochemical detection reaches detection limits at a level of tens of ng/L [188]. Biosensors [189] and immunosensors, miniature instruments based on specific immune recognition and electrochemical detection [190], have been intensively developed in the last few years.…”
