The bio-nanocapsules displaying about 240 molecules of immunoglobulin G Fc-binding Z domains (ZZ-BNCs) enhanced the signals of enzyme-linked immunosorbent assay by tethering the Fc regions of secondary antibodies (Abs), which were eliminated using high-molecular mass enzymes (e.g., alkaline phosphatase). By way of optimizing the distance between enzymes and Abs, ZZ-BNCs improved sensitivity independently of enzymes.
