Electrochemical immunostrip and its preparation method

摘要

An electrochemical immuno diagnostic strip and its preparation method are disclosed herein. A screen-printed electrode is prepared on an insulating substrate, which is divided into an electrode area and a connecting area. An electrochemical precursor is placed on the electrode area and a reaction membrane is provided on the electrode area. A specimen loading area is at the reaction membrane. The present invention is advantageous to overcome the interference problem of the electrochemical detection technology and to provide the quantitative analysis of the prompt diagnostic strip.
