Electrochemical luminescence sensor based on double suppression for highly sensitive detection of glyphosate

Glyphosate sensing in aqueous solutions by fluorescent zinc(ii) complexes of [9]aneN3-based receptors

“…8 Glyphosate can irreversibly inactivate acetylcholinesterase (AChE) to cause different adverse physiological reactions, which might cause respiratory, myocardial, and neuromuscular dysfunctions. 6,9–11 Furthermore, recent studies have indicated that glyphosate is potentially carcinogenic to humans 12 although there are conflicting opinions on its carcinogenicity between the US Environmental Protection Agency (EPA) and the International Agency for Research on Cancer (IARC). 13 The EPA has set the maximum contaminant level (MCL) of glyphosate in drinking water to 4.1 μM.…”

“…13 The EPA has set the maximum contaminant level (MCL) of glyphosate in drinking water to 4.1 μM. 9–14 Finally, 2-amino-4-[hydroxy(methyl)phosphoryl]butanoic acid (H 2 GLU, generally called glufosinate) is a broad-spectrum and fast acting herbicide used to manage glyphosate-resistant weeds mainly because of its broad-spectrum action mode. 15 Although its use has increased exponentially over the past decade, the areas treated with this herbicide are far less than that treated with glyphosate, due to its reduced efficiency against weeds.…”

Highly catalysis amplification of MOFNd-loaded nanogold combined with specific aptamer SERS/RRS assay of trace glyphosate

“…These two scattering spectral methods each have their own advantages; SERS has higher sensitivity, and RRS does not require molecular probes. Compared with the reported methods for detecting GLY, [34][35][36][37][38][39][40] the di-mode scattering method has the advantages of high sensitivity and simplicity (Table S2 †).…”

Recent Advances in the Construction of Flexible Sensors for Biomedical Applications

“…In the report of biosensors, we know that the repeatability of aromatic hydrocarbon biosensors is about 95%, and the repeatability response is only in the concentration range of 5–250 ppm, the sensitivity is 1.645–2.605 Hz ppm −1 , [ 52 ] the linearity of the electrochemical sensor range is 0.01–100 μm, the detection limit is as low as 0.5nm, the stability is placed at 4 °C for 10 days, and the current response of more than 99.2% is retained. [ 53 ] It has good repeatability and the relative deviation (RSD) is 2.02% with high sensitivity up to 265.7 μA m m −1 cm ‐2 . [ 54 ] In another case, Zhao et al.…”
