FRET-based innovative assays for precise detection of the residual heavy metals in food and agriculture-related matrices

Recent advances in the detection and removal of heavy metal ions using functionalized layered double hydroxides: a review

“…As one of the most severe environmental problems, heavy metal pollution causes health risks and is difficult to treat. 1 Even at the ppb level, some heavy metals are still harmful due to their strong binding affinity toward N, O, and S atoms of biomolecules, which inhibits biological functions and interrupts physiological processes. 2 For example, the catalytic activity of some enzymes is dramatically inhibited after Hg 2+ or Cu 2+ binding, which is known as heavy metal poisoning.…”

Efficient Inhibition of Aspergillus flavus to Reduce Aflatoxin Contamination on Peanuts over Ag-Loaded Titanium Dioxide

“…Industrial wastes, pesticides, heavy metals, mycotoxins, etc. are becoming more and more serious threats to food safety [ 1 , 2 , 3 , 4 ]. Peanuts, with rich nutrients and health value, are a type of important oil crop [ 5 ], but they are susceptible to aflatoxin contamination.…”

Nanoassemblies Based on a Cationic Perylene Diimide Derivative and Sodium Dodecyl Sulfate: A Simple Fluorescent Platform for Efficient Analysis of Aflatoxin B1

“…Compared with other analytical methods, fluorescence techniques not only possess the characteristics of facile operation without specialized instrumentation but also exhibit high sensitivity and good selectivity for analytes. 19 were employed for the quantitative detection of AFB 1 in food samples directly. 10,22−24 For instance, Wang et al successfully developed a fluorescent sensing platform based on Al-MOF for the efficient detection of AFB 1 .…”

“…Nowadays, vast endeavors have focused on exploiting a fluorescent strategy for monitoring food contaminants. Compared with other analytical methods, fluorescence techniques not only possess the characteristics of facile operation without specialized instrumentation but also exhibit high sensitivity and good selectivity for analytes. − The fluorophores have a significant effect on the sensing performance of the fluorescent strategy. Currently, some fluorophores (such as metal–organic frameworks and carbon quantum dots) were employed for the quantitative detection of AFB 1 in food samples directly. ,− For instance, Wang et al successfully developed a fluorescent sensing platform based on Al-MOF for the efficient detection of AFB 1 .…”
