(a) Size- and (b) shape-dependent cellular uptake kinetics of Au NP-siRNA constructs. In (a), 13-nm spheres (23 ± 8 AS per NP) and 50-nm spheres (329 ± 42 AS per NP) had similar oligonucleotide densities of ~ 0.16 molecules nm−2. In (b), 50-nm spheres (221 ± 34 AS per NP) and 40-nm stars (251 ± 41 AS per NP) had oligonucleotide densities of ~ 0.13 molecules nm−2.
