Electric-Field-Directed Self-Assembly of Active Enzyme-Nanoparticle Structures

Figure 8

Coupling of bi-enzyme NP layers. The incorporation of both streptavidin-HRP and GOx-avidin into the same layer structure may allow for chemical coupling of the layers. The oxidation of glucose by GOx produces hydrogen peroxide which is then a substrate for the chemiluminescent oxidation of luminol, which generates light that can be detected.
