NOVELTY - This utility new type relates to a measuring one of silk screen printing electrode estriol immune sensor. Wherein the printing plate using printed working electrode, allixiary electrode, a reference electrode, a leading-out wire test instrument by connecting, detect estriol. Working electrode, allixiary electrode, a reference electrode using carbon, carbon, Ag/AgCl doping of ink printing, leading-out wire is conductive silver paste, leading-out wire part covering an insulating layer are orderly arranged silver impurity graphene layer and estriol antibody layer on the working electrode surface, this utility new type sensor manufacturing cost is low, the product can be polished, detect result is stable and detect operation suitable for estriol of disposable, fast, high sensitivity.
