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

Figure 1

Electric-field-directed assembly (layering) of biomolecule NPs by different binding mechanisms: (a) NP layering with alternate biotin (blue)-functionalized NPs and streptavidin (yellow)-functionalized NPs. (b) NP layering by hybridization of complementary DNA sequences. (c) NP layering of biotin-functionalized NPs with streptavidin-functionalized enzymes (brown) (image not to scale).
