Description

technical field [0001] The invention relates to a rapid detection system for immune nano-magnetic separation of bacterial toxins, which belongs to the technical field of food sanitation detection instruments and equipment. Background technique [0002] With the development of science and technology and the continuous improvement of people's living standards, the food industry has developed rapidly. At present, the global food trade volume has reached hundreds of billions of dollars. In order to protect consumers' health and national interests, food safety and sanitation are generally valued by governments of all countries, and governments of all countries strictly limit various harmful substances and ingredients in food to prevent various types of food poisoning. Among all kinds of food poisoning, bacterial food poisoning is the most common, accounting for about half of the total number of food poisoning. Rapid detection of toxins in food is an important means to prevent f...
