Abstract
The present disclosure discloses an intelligent point-of-care testing device for mycotoxins based on a quantum dots test strip. A first light source and a second light source are used for exciting a test strip which is placed in a shell and coated with a mycotoxin antigen to obtain emitted light, and a light filtering component is used for filtering out impurity light. A clamping mechanism is used for clamping and fixing an image capturing component. The image capturing component is used for capturing, an image of mycotoxins based on a quantum dots test strip. A processor is used for analyzing and calculating image information to obtain a mycotoxin content result. The testing time is shortened, and the portability and practicability of mycotoxin testing are improved. Quantitative instant testing of single or multi-toxin mixed pollution is achieved, and the technical problem of fluorescence quantification is solved.
