Objective: To establish a method for the determination of 33 veterinary drug residues in animal-derived foods by ultra performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS). Methods: The samples were extract with acetonitrile-water (80:20, V:V), and purified by QuEChERS....

As a marine food-borne pathogen, Vibrio parahaemolyticus (V. parahaemolyticus) can cause human gastrointestinal disorders and pose a serious threat to food safety and public health worldwide. Using a portable scanner, herein, a real-time fluorescence saltatory rolling circle amplification (RF-SRCA) ...

Contamination of foodborne pathogens is one of the important factors affecting food quality and safety. Therefore, strengthening the monitoring of foodborne pathogens is essential to ensure food safety and prevent foodborne diseases. Compared with traditional culture methods, nucleic acid-based...

Foodborne disease poses an enormous threat to the safety of human beings all over the world. The rapid and accurate monitoring and determination of foodborne pathogenic bacteria is of great significance to food safety. In recent years, with the evolution of nanotechnology, reduced graphene oxide...

In this study, a real -time fluorescent saltatory rolling circle amplification technology combined with propidium monoazide (PMA) was developed for efficient and sensitive detection of live Listeria monocytogenes in milk. Specific primers were designed and screened based on hlyA gene of Listeria...

A novel method for hierarchical screening of illegal adulterants in Fur seal ginseng pills products was developed by multi-dimensional fingerprint profiling analysis. Fingerprint feature of the samples was acquired by high-performance liquid chromatography analysis of 11 batches of samples with...

Food safety has increasingly become an important public health problem. The food-borne diseases, genetically modified foods and falsification of food raw materials have become a common and growing public health problem in both the developed and developing countries. However, the traditional...

Residual tetracycline (TC) in animal food caused by abuse of antibiotics leads to many chronic diseases in the human body. The development of a simple and on-site visualization method for TC detection is need of the hour. Herein, a fluorescent europium-based metal-organic framework (Eu-MOF) sensor...

A magnetic nanoparticle (MNP)-based lateral flow immunochromatography assay (LFIA) was established to detect fluoroquinolones (FQs) in milk. This method is an improvement of traditional Au nanoparticle (AuNP)-based LFIA. Compared with AuNP-labeled antibody, the combination between MNPs and antibody ...

Sensitive and specific detection of Salmonella is highly desirable to guarantee food safety and prevent food-borne disease outbreaks. Herein, we proposed a ratiometric electrochemical biosensor based on the combination of SRCA and CRISPR/Cas12a system for ultrasensitive and specific detection of ...
