Catalytic Microcapsules Assembled from Enzyme-Nanoparticle Conjugates at Oil-Water Interfaces

Involuntary association: Anionic β-galactosidase enzymes associate with positively charged Au nanoparticles to produce reduced-charge conjugates, which assemble at oil-water interfaces to result in stable microcapsules (see picture). The microcapsules were formed quickly and showed high enzymatic ac...

Zusammenfassung:Involuntary association: Anionic β-galactosidase enzymes associate with positively charged Au nanoparticles to produce reduced-charge conjugates, which assemble at oil-water interfaces to result in stable microcapsules (see picture). The microcapsules were formed quickly and showed high enzymatic activity, which makes them promising materials for biotechnology applications.
