Figure 2: Characterization of PTX and TET co-loaded LPN.

(A) Particle size distribution measured by DLS and TEM image of LPN. (Top-right) The magnified view of LPN showing the core-lipid shell structure; (B) Stability of conjugated P+T/iRGD LPN* and unconjugated P+T/iRGD LPNâ–² in PBS or 10% FBS for 14 days storage; (C) in vitro release of PTX and TET in response to redox environment.
