Description

technical field

[0001] The invention belongs to the technical field of analysis and detection, and in particular relates to a preparation method of an estradiol magnetic molecule imprinted nanoparticle electrochemical sensing membrane (MMIES). Background technique

[0002] 17-βestradiol (E2) is one of the endocrine disruptors. Studies have shown that children with precocious puberty, male prostate cancer, women's breast cancer and uterine cancer incidence are all related to estrogen residues in food. In addition, it will also affect the physiological laws of women, and even cause infertility. Trace levels of estradiol can cause disorders of humoral immunity and cellular immunity, resulting in reproductive immunity, cardiovascular and nervous system lesions. However, due to the residue and illegal addition of estrogen in the production process, it often causes problems such as environmental pollution and food safety. In order to ensure the health of consumers and regulate t...
