“…Due to LSPR properties, noble metal nanoparticles are allowed to display an adjustable multicolor change which is intimately linked to the size, composition, interparticle distance of the nanostructure, and surrounding environment (Guo et al, 2015). Sharief et al reported an equipment-free bacterial detection strategy that combined the bacterial capture performance of glycan-coated magnetic nanoparticles with the genomic DNA detection performance of dextrin-capped AuNPs (Sharief et al, 2023). Due to the hybridization reaction between target…”

“…Sharief et al. reported an equipment‐free bacterial detection strategy that combined the bacterial capture performance of glycan‐coated magnetic nanoparticles with the genomic DNA detection performance of dextrin‐capped AuNPs (Sharief et al., 2023). Due to the hybridization reaction between target Escherichia coli DNA and single‐stranded probe on AuNPs, the stability of AuNPs is enhanced and the AuNPs in solution can be controlled from aggregated to nonaggregated state.…”

Food contaminants have consistently posed a serious threat to human health and have caused various food safety problems. The most common techniques currently used for the detection of food contaminants, include instrumental and immunoassay methods; however, these traditional methods have shown some limitations when applied to the analysis of food contaminants. Therefore, in recent years, more and more researchers have been devoted to the development of rapid, reliable, sensitive, and suitable detection techniques for the detection of food contaminants in food matrices. In this review, we first classify the analytical methods proposed in recent years into colorimetric methods, fluorescence methods, photoelectrochemical methods, electrochemical methods, nucleic acid amplification methods, and other methods, and illustrate their detection principles. In addition, the paper highlights the strategies and recent research advances for each method through typical application examples. Finally, the future perspectives of these analytical methods are presented. We hope that this review will provide researchers with valuable insights to guide the sensitive detection of food contaminants.

“…For instance, thiol-capped GNPs were used to detect Klebsiella pneumoniae within one hour using an amplified K2A gene [ 165 ] and the unamplified DNA of uropathogenic E. coli [ 168 ]. Dextrin-coated GNPs were used earlier to detect the unamplified DNA of E. coli O157:H7 [ 164 ], E.coli [ 169 ], Salmonella Enteritidis [ 170 ], and Pseudoperonospora cubensis [ 171 ] within 30 min. Further, dextrin-coated GNPs have recently been used to detect KPC-producing bacteria (~10 3 CFU/mL) from clinical isolates with 79% sensitivity and 97% specificity [ 172 ].…”

Infectious disease outbreaks have caused thousands of deaths and hospitalizations, along with severe negative global economic impacts. Among these, infections caused by antimicrobial-resistant microorganisms are a major growing concern. The misuse and overuse of antimicrobials have resulted in the emergence of antimicrobial resistance (AMR) worldwide. Carbapenem-resistant Enterobacterales (CRE) are among the bacteria that need urgent attention globally. The emergence and spread of carbapenem-resistant bacteria are mainly due to the rapid dissemination of genes that encode carbapenemases through horizontal gene transfer (HGT). The rapid dissemination enables the development of host colonization and infection cases in humans who do not use the antibiotic (carbapenem) or those who are not hospitalized but interacting with environments and hosts colonized with carbapenemase-producing (CP) bacteria. There are continuing efforts to characterize and differentiate carbapenem-resistant bacteria from susceptible bacteria to allow for the appropriate diagnosis, treatment, prevention, and control of infections. This review presents an overview of the factors that cause the emergence of AMR, particularly CRE, where they have been reported, and then, it outlines carbapenemases and how they are disseminated through humans, the environment, and food systems. Then, current and emerging techniques for the detection and surveillance of AMR, primarily CRE, and gaps in detection technologies are presented. This review can assist in developing prevention and control measures to minimize the spread of carbapenem resistance in the human ecosystem, including hospitals, food supply chains, and water treatment facilities. Furthermore, the development of rapid and affordable detection techniques is helpful in controlling the negative impact of infections caused by AMR/CRE. Since delays in diagnostics and appropriate antibiotic treatment for such infections lead to increased mortality rates and hospital costs, it is, therefore, imperative that rapid tests be a priority.
