Abstract :
[en] Background: Inadequate or untimely food safety detection and monitoring technologies often lead to substantial resource and cost wastage. Consequently, the development and implementation of portable, rapid, and intelligent technologies have become critical to ensure food safety and the preservation of product quality. Layered 19 double hydroxides (LDHs), due to their large specific surface area, excellent stability, 20 simple synthesis methods, and low cost, have garnered significant attention from 21 researchers in recent years. LDHs have emerged as an ideal choice for achieving high 22 sensitivity and strong specificity in food safety sensing and detection. 23 Scope and approach: A detailed overview of the fundamental concepts of LDHs is 24 provided, accompanied by a comprehensive analysis of their synthesis methods. Next, 25 the sources of catalytic activity in LDHs are explored, and strategies for regulating their 26 performance are proposed to enhance their effectiveness in food contaminant detection. 27 Finally, the progress in practical applications of LDHs for detecting various food 28 contaminants is reviewed, with an emphasis on their effectiveness in improving 29 detection sensitivity, increasing detection efficiency, and facilitating the development 30 of portable and intelligent detection systems. 31 Key findings and conclusion: LDHs can be applied in the detection of heavy metals, 32 pesticide residues, mycotoxins, and antibiotics. However, LDHs still face certain 33 limitations in achieving high sensitivity and strong specificity in detecting target 34 substances. One promising strategy to overcome these challenges is the synergistic 35 incorporation of high-performance catalytic materials, such as single- or dual-atom 36 catalysts and other nanomaterials. This development not only offers new perspectives 37 for advancing food safety detection technologies but also expands the possibilities for 38 broader applications of LDHs.
