Physicochemical and morphological characterization of scCD98-functionalized NPs. Agarose gel electrophoresis of NPs with different weight ratios: (A) scCD98-functionalized NPs prepared by scCD98-PEG-UAC and scrambled siRNA; (B) scCD98-functionalized NPs fabricated by scCD98-PEG-UAC and scrambled siRNA with different amounts of PEI (2 kDa). Particle sizes (C) and zeta potential (D) of scCD98-functionalized NPs with different weight ratios measured by dynamic light scattering. Each point represents the mean ± S.E.M. (n = 3). The height scanning profile (E) and topographical data (F) of atomic force micrograph show scCD98-functionalized NPs (weight ratio, 40:20:1). Scale bar represents 500 nm.
