Description

Technical Field

[0001] The utility model relates to the field of food testing equipment, and more specifically to a dual-mode colloidal gold detector. Background Art

[0002] Colloidal gold testing is a new type of immunolabeling technology that uses colloidal gold as a tracer marker for antigens and antibodies, and has its own unique advantages. It has been widely used in various biological studies in recent years. Colloidal gold labeling is essentially a coating process in which macromolecules such as proteins are adsorbed onto the surface of colloidal gold particles. The adsorption mechanism may be that the negative charge on the surface of the colloidal gold particles forms a strong bond with the positively charged groups of the protein due to electrostatic adsorption. The reduction method can easily prepare colloidal gold particles of various particle sizes, that is, different colors, from chloroauric acid. This spherical particle has a strong adsorption function for proteins and can be non-covalently bound to staphylococcal protein A, immunoglobulins, toxins, glycoproteins, enzymes, antibiotics, hormones, bovine serum albumin polypeptide conjugates, etc., so it is also used in food safety testing.

[0003] If you eat food containing residual pesticides and harmful substances, these harmful substances cannot be excreted from the body and will remain in the human body, which will directly endanger people's health. With the increasing attention paid to food safety, the efficiency of the equipment that needs to be tested cannot meet the existing testing needs. Utility Model Content

The detection assembly 5 is installed on the driving assembly 4, and the driving assembly 4 drives the detection assembly 5 to scan the first card assembly 2 and the second card assembly 3 one by one. The number of detections is increased by arranging the first card assembly 2 and the second card assembly 3, and the detection efficiency is higher by realizing that the detection assembly 5 detects the first card assembly 2 and the second card assembly 3 one by one through the driving assembly 4.

[0022] The first card insertion assembly 2 includes a plurality of card slots, which are regularly arranged in a row, and the card slots are provided with 6-10. The first card insertion assembly 2 and the second card insertion assembly 3 are symmetrically arranged, and the structure of the first card insertion assembly 2 is the same as that of the second card insertion assembly 3.
