Abstract: Disclosed are a SA@CDs/g-C3N4 composite material, a method for preparing same, and an application of the same to aflatoxin removal, which belong to the technical field of organic materials. The method for preparing a SA@CDs/g-C3N4 composite material includes: adding a CDs/g-C3N4 compound into water, and uniformly dispersing same through ultrasonic treatment; adding sodium alginate, intensely stirring and fully mixing a mixture, and forming a pregel solution; transferring the fully mixed pregel solution into a mold, and freeze-drying the pregel solution to obtain sponge; and soaking the sponge in a CaCl2) solution for gel, performing washing with deionized water, performing freeze-drying, and obtaining the SA@CDs/g-C3N4 composite material. The SA@CDs/g-C3N4 composite material prepared according to the present disclosure can effectively remove residual aflatoxin in foods, and is wild in effect, environmentally-friendly and safe.

Abstract: The invention displays aflatoxin B1 (AFB1) detection kit and AFB1 detection method. The invention belongs to the technical field of detecting harmful substances. The AFB1 detection kit was fabricated with DNA walker structure, endonuclease, hairpin H1 and H2. The AFB1 detection kit has benefits of high sensitivity and short detection time based on signal amplification strategy of DNA Walker structure and hyperbranched fluorescent nanotrees. The present invention can realize high sensitive and rapid detection of AFB1.
