A DLS size distribution spectrum of PLNEs fed with varying amounts of PTX. B PTX encapsulation and loading efficiencies for various formulations of PLNE-PTX. C TEM image of the optimized PLNE-PTX formulation. D Stability of PLNE-PTX as assessed by changes in size and PDI in ddH2O at 4 °C. E Serum stability of PLNE-PTX at 37 °C for 24 h in 50% FBS or DPBS, assessed by fluorescence quenching efficiency. F PTX release from PLNE-PTX relative to the commercially available Taxol was evaluated by PTX leakage study at 37 °C (*** p < 0.001, n = 3 per group)
