Pd/Cu-TCPP(Fe)-polydopamine mediated magnetic relaxation switching immunosensor for sensitive detection of chlorpyrifos.

J Hazard Mater

December 2024

State Key Laboratory of Marine Food Processing and Safety Control, Academy of Food Interdisciplinary Science, School of Food Science and Technology, Dalian Polytechnic University, Dalian, Liaoning 116034, PR China. Electronic address:

This study presents the development of a magnetic relaxation switching (MRS) immunosensor for the sensitive detection of chlorpyrifos (CPF) with a signal amplification strategy using Pd/Cu-TCPP(Fe) hybrid nanosheets and polydopamine (PDA). Pd/Cu-TCPP(Fe) nanosheets, which exhibit high peroxidase-like activity and excellent storage stability, making them suitable replacements for natural enzymes in biosensors, are further functionalized with goat anti-mouse IgG (Ab) to construct an immunosensor. The mechanism relies on the competition between free CPF and the immobilized bovine serum albumin-CPF conjugates for antibody binding, which modulates the aggregation of magnetic nanoparticles (MNPs) that are related to the transverse relaxation time.

Introduction: Cauliflower is widely cultivated all over the world is attributed to its palatable flavor, high levels of anti-cancer compounds, and diverse array of nutrients. Exposure to extremely cold stress during production can result in a more frequent occurrence of purple discoloration in cauliflower curds. In response to cold stress, plants naturally produce anthocyanins to eliminate reactive oxygen species (ROS) generated as a defense mechanism.

N-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs) are essential for physiological requirements and disease prevention throughout life but are not adequately consumed worldwide. Dietary supplementation with plant-derived α-linolenic acid (ALA) has the potential to rebalance the fatty acid profile and enhance health benefits but faces challenges such as high β-oxidation consumption, low hepatic conversion efficiency, and high oxidative susceptibility under stress. This review focuses on the metabolic fate and potential regulatory targets of ALA-containing lipids , specifically the pathway from the gastrointestinal tract to the lymph, blood circulation, and liver.

Article Synopsis
  • Eutrophication is a major environmental issue for global lakes, heavily influenced by the presence and composition of particulate organic matter (POM).
  • The study characterized POM from seven Yangtze River lakes, revealing it primarily originates from autochthonous sources (62.7%) and showing that labile compounds increase as trophic states rise.
  • Findings suggest that as lake eutrophication progresses, the increased presence of autochthonous POM and labile compounds may further exacerbate the eutrophication process through positive feedback mechanisms.
