Biological multilayer films of redox polymer and horseradish peroxidase (HRP) were successfully assembled on a screen-printed carbon electrode using layer-by-layer (LBL) assembled method based on the electrostatic interaction. The screen-printed carbon electrode surface was modified by the positively charged redox polymer, and the negatively charged HRP by LBL method.

Using layer-by-layer (LBL) assembled method, multilayer films containing multiwall carbon nanotubes (MWNTs) and redox polymer were successfully fabricated on a screen-printed carbon electrode. X-ray photoelectron spectroscopy (XPS) and field-emission scanning electron microscopy (FE-SEM) were used to characterize the assembled multilayer films.
