Figure 2.

In vitro characterization of PN, PEGylated PN, and the PNM. (A) and (B) showed the morphology of nod-shaped PN and spherical-shaped PN by TEM, respectively; (C) and (D) represented particle size distribution of PEGylated PN and the PNM, respectively, measured by DLS and TEM; (E) Comparison of average particle size of PN, PEGylated PN, and the PNM; (F) Zeta potential of PN, PEGylated PN, and the PNM; (G) SDS-PAGE gel analysis of protein content in PN, PEGylated PN, and the PNM referred to RBC lysate; the error bars indicated ± SD (n = 3).
