Table 1. Hydrodynamic diameter, ζ potential, and PNA loading in NPs.

The data are shown as means ± SD (n = 3). Scr-sγPNA/NNP was the physical mixture of Scr-sγPNA-21–loaded NNP and Scr-sγPNA-10b–loaded NNP, sγPNA/BNP was the mixture of sγPNA-21–loaded BNP and sγPNA-10b–loaded BNP, and PNA/BNP was the mixture of PNA-21–loaded BNP and PNA-10b–loaded BNP. NNP indicates PLA-HPG NP, and BNP indicates PLA-HPG-CHO NP.
