A dual-emission carbon dots-based nonenzymatic fluorescent sensing platform for simultaneous detection of parathion-methyl and glyphosate

Ligand Emission-Based Turn-On Sensing of Glyphosate via Competitive Coordination with NH2-MIL-88B (Fe) MOF Nanocrystals

“…The limit of detection (LOD, calculated as 3σ/ K , where σ represents the standard deviation of the MOF (blank) emission and K is the slope of the linear calibration plot) was estimated as 198 nM. Table S1 compares the LOD values obtained in recent studies and the present work. − …”

Rapid detection of multiple antibiotics in chicken samples via a fluorescence nanobiosensor coupled with a homemade fluorescence analyzer

“…It is worth pointing out that the entire procedures, from sample entry to data exit, involving facile sample treatment, simple sample incubation, and automatic sample analysis, took about 1 h. Specically, the recommended uorescence analyzer enabled automatic sampling detection of 10 samples within 5 min in one round, considerably enhancing the analysis efficiency in comparison to a traditional uorescence spectrophotometer which involves manual and single analysis (time-consuming and labor-intensive). 37,38 Moreover, the homemade uorescence analyzer is competent to multiplex quantitative analysis, whereas the widely used handheld spectrometer for lateral ow assays only allows a single sample analysis in addition to a semi-quantitative result. 39 These features of high selectivity and sensitivity, ease of use, and multiplexity make the developed uorescence biosensing platform show great promise for further practical applications.…”

Construction of a novel fluorescent probe for sensitive determination of glyphosate in food and imaging living cells

“…[4][5][6] Glyphosate is harmful to the human body, causing damage to a person's liver and kidneys, as well as damage to the mucous membranes of the skin of the digestive tract. [7][8][9][10][11][12] In serious cases, glyphosate can damage the respiratory system and cardiovascular system, even endangering life. If pregnant women are exposed to glyphosate for a long period of time, it can cause defects in their babies.…”

“…[16][17][18][19][20] In contrast, the uorescence method is widely used for the detection of glyphosate due to its advantages of high sensitivity, simplicity, economy, rapidity and stable signal. [20][21][22][23][24][25][26][27] In recent years, based on the strong complexation ability of glyphosate to metal ions, researchers have designed and developed a series of analytical methods based on "turnon" detection of glyphosate from quantum dots and organic uorescent dyes, [28][29][30][31] as shown in Table S1. † Although great efforts have been made in this area, sensitivity and simplicity still need to be improved, and there is still a high demand for new chemical methods that enable probes to be easily synthesised.…”
