A colorimetric biosensor with infrared sterilization based on CuSe nanoparticles for the detection of O157:H7 in food samples.

Unlabelled: It is critical to develop quick, accurate, and efficient sterilization for detecting O157:H7 in order to prevent infections and outbreaks of foodborne illnesses. Herein, we established a colorimetric biosensor with sterilizing properties using copper selenide nanoparticles to detect O157:H7. The sample was mixed with magnetic nanoprobes and nanozyme probes to form a sandwich structure, and then the unbound nanozyme probes were collected by magnetic separation.

The Application of Hybridization Chain Reaction in the Detection of Foodborne Pathogens.

Today, with the globalization of the food trade progressing, food safety continues to warrant widespread attention. Foodborne diseases caused by contaminated food, including foodborne pathogens, seriously threaten public health and the economy. This has led to the development of more sensitive and accurate methods for detecting pathogenic bacteria.

Phytochemical reduces toxicity of PM2.5: a review of research progress.

Studies have shown that exposure to fine particulate matter (PM2.5) affects various cells, systems, and organs in vivo and in vitro. PM2.

Application of ATP-based bioluminescence technology in bacterial detection: a review.

With the development of new technologies for rapid and high-throughput bacterial detection, ATP-based bioluminescence technology is making progress. Because live bacteria contain ATP, the number of bacteria is correlated with the level of ATP under certain conditions, so that the method of luciferase catalyzing the fluorescence reaction of luciferin with ATP is widely used for the detection of bacteria. This method is easy to operate, has a short detection cycle, does not require much human resources, and is suitable for long-term continuous monitoring.

Lithium chloride's inhibition of 3T3-L1 cell differentiation by regulating the Wnt/β-catenin pathway and enhancing villin 2 expression.

The aim of this study is to reveal the relation among villin 2, Wnt/β-catenin, and adipogenesis by adding appropriate lithium chloride (LiCl). The study comprises three parts: the selection of LiCl concentration, the effect of LiCl on adipocyte differentiation during and after differentiation induction. By comprehensively analyzing the results of the experiments, we proved that LiCl can inhibit adipocyte differentiation and enhance villin 2 and β-catenin expressions not only during differentiation induction but also after it.
