(A) Relative size of ND–Ab complexes expressed as a weight ratio of ND : Ab. (B) Depiction of ND to Ab aggregate zeta potential measurements revealing innate stability of formed ND–Ab complexes compared to Ab alone. Increasing the amount of NDs does not significantly alter complex stability, supporting a 2 : 1 ratio as optimal to adsorb Ab to the ND surface.
