Controllable synthesis of bifunctional magnetic carbon dots for rapid fluorescent detection and reversible removal of Hg2+

Deltamethrin and fenvalerate in vegetables and rice

“…[20][21][22] Though, some challenges in their use remain, such as stability, biocompatibility, and toxicity. Hence, in comparison to other analytical techniques, CD-based uorescence methods have emerged as highly efficient tools for detecting pesticides, [23][24][25] heavy metal ions, 26,27 biomarkers, and drugs. 28 Despite the promising applications for broad use in pesticide analysis, the advancement of optical sensors utilizing CDs technology still faces challenges, like the quantum yield (QY), uorescence performance, development of green synthesis methods, purication process, modication in the synthesis methods to tune the optical properties, large-scale production, and real-life applications.…”

Carbon Dot-Based Ratiometric Fluorescent Probe Platform for Visual Quantitative Determination of Hg2+

“…1 Hg pollution poses a serious threat to life in nature, especially human health as well as environmental safety. 2 Hg 2+ can eventually reach the human body through the food chain due to its high bioaccumulation effect, even trace levels of Hg 2+ can cause irreversible damage to the human liver, kidney, endocrine system, and nervous system. 3 Considering the toxic effects of Hg 2+ , strict standards were established by the United States Environmental Protection Agency (EPA) and World Health Organization (WHO), which stipulate the maximum allowable Hg 2+ level in drinking water is 10 nM and 30 nM, respectively.…”

“…Mercury (Hg) is considered as one of the most representative hazardous contaminants owing to its high toxicity, bioaccumulation, and nonbiodegradation . Hg pollution poses a serious threat to life in nature, especially human health as well as environmental safety . Hg 2+ can eventually reach the human body through the food chain due to its high bioaccumulation effect, even trace levels of Hg 2+ can cause irreversible damage to the human liver, kidney, endocrine system, and nervous system .…”

Highly sensitive and selective SERS substrates with 3D hot spot buildings for rapid mercury ion detection

“…4–6 In the past decades, various analytical techniques, including chromatography, electrochemical methods, atomic absorption spectrometry, atomic emission spectrometry, and fluorescence spectrometry, for detecting and analyzing Hg 2+ have been reported. 7–11 Although these analytical methods are effective in measuring complicated samples, they require large equipment, professional operators, and time-consuming sample preparation during their detection processes, making them unsuitable for achieving rapid and on-site detection for Hg 2+ . Therefore, it is crucial to provide an effective approach with high sensitivity and specificity for achieving Hg 2+ detection.…”
