The invention relates to a preparation method and application of an unmarked immunosensor for rapidly detecting clenbuterol. Clenbuterol means a medicine of a beta-stimulant type instead of a specific medicine, and has the functions of prompting lean meat growth and suppressing fat meat growth as well as extremely serious side effects, and when a large amount of clenbuterol is taken, the cardiovascular system of people can be damaged and severe neurological symptoms can be caused. According to the invention, a gold-silver-sulfide nano composite material modified electrode with a core-shell structure which combines the excellent characteristics of nano gold and nano silver sulfide is adopted for preparing the unmarked immunosensor, and a clenbuterol antibody is well immobilized, so that the unmarked immunosensor is low in cost, high in sensitivity, good in specificity, rapid in detection and simple to prepare. |
