Electrochemical Analysis of Enzyme Based on the Self-Assembly of Lipid Bilayer on an Electrode Surface Mediated by Hydrazone Chemistry

In this work, a new strategy for electrochemical analysis of enzyme has been proposed based on a self-assembled lipid bilayer on an electrode surface mediated by hydrazone chemistry. Taking aldolase as an example, the enzyme can catalyze the formation of products containing carbonyl groups. These groups can react with hydrazine groups of the functional lipid derivative, resulting in the self-assembly of a lipid bilayer on a guanidinium modified electrode surface. The lipid bilayer will then prevent the movement of hydrophilic electrochemical probes. Consequently, the catalytic reaction of the enzyme may result in the change of the obtained electrochemical peak current. Experimental results reveal that aldolase activity can be analyzed over a widely linear detection range from 5 mU/L to 100 U/L with a low detection limit of 1 mU/L. Meanwhile, the method can exhibit good precision and reproducibility and it can be applied for real sample analysis. What is more, because the lipid bilayer is the universal basis for cell-membrane structure, while hydrazone chemistry is popular in nature, this work may also provide a new insight for the development of electrochemical analysis and electrochemical biosensors.
