A glucose sensor electrode, a preparation method therefor and the use thereof are provided for the rapid and sensitive detection of glucose. The method involves: (1) performing an alkali heat treatment to form a nanoneedle-structured titanium dioxide on the surface of a titanium electrode; (2) forming micro-region grooves on a nanoneedle-structured titanium dioxide film layer to obtain a nanoneedle-structured titanium dioxide having a micropattern; (3) depositing a chlorine-doped polypyrrole in the grooves by using chronopotentiometry; (4) forming a nanocone-structured citric-acid-doped polypyrrole on the chlorine-doped polypyrrole by using chronopotentiometry; and (5) grafting an enzyme capable of detecting glucose to obtain the glucose sensor electrode. This simple and stable process is low in cost, efficiently grafts the enzyme capable of detecting glucose on the surface of the electrode, and provides a stable electrode with higher reliability for detecting glucose.
