Abstract: The multilayers were constructed by the strong lection glycoprotein specific interaction and were used in the preparation of glucose biosensors. The results showed that the glucose oxidase with glucose residues and hydrogen peroxidase without glucose residues could be assembled into multilayers. The thickness of multiplayer films increased linearly with the increase of the layers. The morphology was investigated, and the relationship between film structure and function was discussed. The study on electrochemistry of gold electrode of lectin enzyme multiplayer shows that the enzyme in multilayers remains the catalytic activity.
