To enhance the sensitivities and antigen-binding capacities of immunosensors, oriented immobilization of antibodies on the surface of the sensor chip is critical, but to date, this has not been adequately achieved. We describe a way of adsorbing immunoglobulin (Ig) proteins onto 32-nm bio-nanocapsules (BNCs) through IgG Fc-binding domains derived from Staphylococcus aureus protein A (ZZ-BNC). This arrangement permits approximately 60 molecules of mouse total IgG bind to ZZ-BNC and all the IgG Fv regions to be displayed outwardly for the effective binding of antigens. ZZ-BNCs adsorbed onto the gold surface of the sensor chip of the quartz crystal microbalance (QCM) could markedly enhance the sensitivity and antigen-binding capacity of the chip. On the sensor chip of surface plasmon resonance (SPR), antibodies on the ZZ-BNCs showed higher affinities to each antigen than those on protein A. The BNC-coated sensor chip is very stable, and should prove useful for various immunosensor applications due to oriented immobilization of antibodies.
