(A) ELISA adsorption results. Addition of NDs to Ab solutions under dilute saline conditions showed a decreased amount of free Ab following ND–Ab complex isolation. As the ratio of NDs to Ab increased, more complexes formed thus further reducing the Ab concentration remaining in free solution. (B) UV-vis Ab adsorption results. Absorbance values taken at 280 nm indicative of protein concentration reveal Ab adsorption to NDs. These results confirm ND–Ab complex formation as indicated through ELISA.
