Abstract
Ratiometric electrochemical sensors are renowned for their dual-signal processing capabilities, enabling automatic correction of background noise and interferences through built-in calibration, thus providing more accurate and reproducible measurements. This characteristic makes them highly promising for food analysis. This review comprehensively summarizes and discusses the latest advancements in ratiometric electrochemical sensors and their applications in food analysis, emphasizing their design strategies, detection capabilities, and practical uses. Initially, we explore the construction and design strategies of these sensors. We then review the detection of various food-related analytes, including nutrients, additives, metal ions, pharmaceutical and pesticide residues, biotoxins, and pathogens. The review also briefly explores the challenges faced by ratiometric electrochemical sensors in food testing and potential future directions for development. It aims to provide researchers with a clear introduction and serve as a reference for the design and application of new, efficient ratiometric electrochemical sensors in food analysis.

Poult Sci 2024; 103:104316. [PMID: 39383667 DOI: 10.1016/j.psj.2024.104316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2024] [Revised: 09/03/2024] [Accepted: 09/05/2024] [Indexed: 10/11/2024] Open
Abstract
Aflatoxin B1 (AFB1) a mycotoxin found in chicken feed that possess a global hazard to poultry health. However different potent compounds like bovine lactoferrin (bLF) may prove to be protective effects against AFB1. This study aims to explore the protective effect of bLF against AFB1-induced injury in the liver and kidney in broiler. For this purpose, 600 broilers chicks were randomly alienated into 5 groups (n = 120 each): negative control; positive control (3 mg/kg AFB1), and bLF high, medium, and low dosage groups (600 mg/kg, 300 mg/kg, and 150 mg/kg, respectively). The results highlight that AFB1 toxicity in birds exhibited low feed intake, reduction in weight gain, and a decrease in FCR while, bLF regulated these adverse effects. Meanwhile, AFB1 group showed higher levels of alanine transaminase (ALT) and aspartate aminotransferase (AST) and lower levels of superoxide dismutase (SOD) and glutathione (GSHpx) in liver, while urea and creatinine were decline in kidney. Supplementation with bLF effectively controlled these biomarkers and control the negative effects of toxicity. Furthermore, hematoxylin and eosin (H&E) staining exhibited normal morphological structures within liver and kidney in the bLF treated groups, while degenerative changes were observed in AFB1 group. Similarly, bLF, decreased oxidative stress and thus prevented apoptosis in the liver and kidney cells of the birds. Whereas, mRNA level of mitochondrial apoptosis related gene including Bcl-2 (Bak and Bax), caspase-3 and caspase-9 was upregulated, while bcl2 gene were downregulated in AFB1 group. Dietary supplementation of bLF effectively normalizes the expression of these genes. AFB1 exposed birds shown to decrease gene expression level of the crucial component of Nrf2 pathway, responsible to regulate antioxidant defense. Interestingly, bLF reverse these detrimental effects of and restore the normal expression levels of Nrf2 pathway. Conclusively, our findings demonstrate that bLF mitigates the detrimental effects of AFB1, besides regulation of the apoptosis-related genes via mitochondrial pathways. These findings validate that the bLF (600 mg/kg) could be used as protective agent against AFB1-induced liver and kidney damage.

Zhang KK, Wan JY, Chen YC, Cheng CH, Zhou HQ, Zheng DK, Lan ZX, You QH, Sun J. Polystyrene nanoplastics exacerbate aflatoxin B1-induced hepatic injuries by modulating the gut-liver axis. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 935:173285. [PMID: 38772488 DOI: 10.1016/j.scitotenv.2024.173285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 05/13/2024] [Accepted: 05/14/2024] [Indexed: 05/23/2024]
Abstract
Dietary pollution of Aflatoxin B1 (AFB1) poses a great threat to global food safety, which can result in serious hepatic injuries. Following the widespread use of plastic tableware, co-exposure to microplastics and AFB1 has dramatically increased. However, whether microplastics could exert synergistic effects with AFB1 and amplify its hepatotoxicity, and the underlying mechanisms are still unelucidated. Here, mice were orally exposed to 100 nm polystyrene nanoplastics (NPs) and AFB1 to investigate the influences of NPs on AFB1-induced hepatic injuries. We found that exposure to only NPs or AFB1 resulted in colonic inflammation and the impairment of the intestinal barrier, which was exacerbated by combined exposure to NPs and AFB1. Meanwhile, co-exposure to NPs exacerbated AFB1-induced dysbiosis of gut microbiota and remodeling of the fecal metabolome. Moreover, NPs and AFB1 co-exposure exhibited higher levels of systemic inflammatory factors compared to AFB1 exposure. Additionally, NPs co-exposure further exacerbated AFB1-induced hepatic fibrosis and inflammation, which could be associated with the overactivation of the TLR4/MyD88/NF-κB pathway. Notably, Spearman's correlation analysis revealed that the exacerbation of NPs co-exposure was closely associated with microbial dysbiosis. Furthermore, microbiota from NPs-exposed mice (NPsFMT) partly reproduced the exacerbation of NPs on AFB1-induced systemic and hepatic inflammation, but not fibrosis. In summary, our findings indicate that gut microbiota could be involved in the exacerbation of NPs on AFB1-induced hepatic injuries, highlighting the health risks of NPs.

Quantitative Determination of Aflatoxin B 1 in Maize and Feed by ELISA and Time-Resolved Fluorescent Immunoassay Based on Monoclonal Antibodies. Foods 2024; 13:319. [PMID: 38275686 PMCID: PMC10815167 DOI: 10.3390/foods13020319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Revised: 01/14/2024] [Accepted: 01/15/2024] [Indexed: 01/27/2024] Open
Abstract
In this study, a highly sensitive monoclonal antibody (mAb) was developed for the detection of aflatoxin B1 (AFB1) in maize and feed. Additionally, indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) and time-resolved fluorescence immunoassay assay (TRFICA) were established. Firstly, the hapten AFB1-CMO was synthesized and conjugated with carrier proteins to prepare the immunogen for mouse immunization. Subsequently, mAb was generated using the classical hybridoma technique. The lowest half-maximal inhibitory concentration (IC50) of ic-ELISA was 38.6 ng/kg with a linear range of 6.25-100 ng/kg. The limits of detections (LODs) were 6.58 ng/kg and 5.54 ng/kg in maize and feed, respectively, with the recoveries ranging from 72% to 94%. The TRFICA was developed with a significantly reduced detection time of only 21 min, from sample processing to reading. Additionally, the limits of detection (LODs) for maize and feed were determined to be 62.7 ng/kg and 121 ng/kg, respectively. The linear ranges were 100-4000 ng/kg, with the recoveries ranging from 90% to 98%. In conclusion, the development of AFB1 mAb and the establishment of ic-ELISA for high-throughput sample detection, as well as TRFICA for rapid detection presented robust tools for versatile AFB1 detection in different scenarios.
