Development of a pH-Responsive, SO42–-loaded Fe and N co-doped carbon quantum dots-based fluorescent method for highly sensitive detection of glyphosate

Ratiometric colorimetric detection of nitrite using CoMnO3 nanofibers as an oxidase-like enzyme to induce diazotization reaction

“…2b), the absorption bands at 3420, 1620, 1400, 1045, and 880 cm −1 were attributed to the stretching vibrations of the O–H, CC, CO, C–O, and δ(CO 3 ), respectively, in CMO. 28 The characteristic vibrations of Co–O and Mn–O coordination bonds could be seen at 625 and 480 cm −1 , respectively. 22 Hence, the distinctive vibrational peaks of organic groups may be due to the presence of trace amounts of acetate from the MnAc 2 precursor.…”

Multifunctional Probe Based on CTAB-Cu Nanoparticles for Fluorescence and Colorimetric Dual-Read-Out Determination of p-Nitrophenol and Glyphosate

“…The presence of chemical groups of CTAB, naked Cu NPs, and CTAB-Cu NPs was further investigated by Fourier transform infrared spectra (FTIR). As shown in Figure B, the O–H stretching vibrations at 3461 cm –1 , the CO stretching vibrations at 1600 cm –1 , and the C–O stretching vibrations at 1060 cm –1 were observed only in the spectra of naked Cu NPs and CTAB-Cu NPs, owing to the presence of the reducing agent glucose. − These oxygen-rich groups improved the solubility of nanomaterials. Moreover, the peaks at 2917–2849 and 1480 cm –1 were attributed to the stretching vibrations of C–H and N + –CH 3 , respectively.…”

Systemic Analysis of Glyphosate Impact on Environment and Human Health

“…Due to the existence of the shikimate pathway, glyphosate had fatal effects on plants but was less harmful to humans and other animals at even high concentrations. For terrestrial and aquatic animals, the concentration of glyphosate dosage ranges from 175 to 540 mg and from 1 to 53 mg, respectively. , Although glyphosate-based herbicides are not easily absorbed via the skin in humans, they are consumed indirectly through the consumption of crops that have been treated with them. The accumulation of glyphosate-based formulations found in urine and faeces that do not degrade into other substances is a significant health hazard caused by glyphosate absorption or ingestion .…”
