漆酶修饰电极的氧还原效率取决于用于将酶结合到表面的寡肽连接物的手性。同时，利用带/不带偶氮苯的氨基酸衍生物席夫碱配体铜（II）配合物作为介质，改善了阴极电极与酶之间的电子传递。在O2和N2条件下电化学电流的增加证明两种介质都对酶有活性。
The oxygen reduction efficiency of a laccase-modified electrode was found to depend on the chirality of the oligopeptide linker used to bind the enzyme to the surface. At the same time, the electron transfer between the cathode electrode and the enzyme is improved by using a copper(II) complex with amino-acid derivative Schiff base ligand with/without azobenzene moiety as a mediator. The increased electrochemical current under both O2 and N2 proves that both the mediators are active towards the enzyme.
