Fig. 5. Effect of sonication amplitude and injection speed on nanoparticles prepared by the emulsification and nanoprecipitation techniques, respectively. Diameter size and PDI as function of sonication amplitude (A), and the injection speed (B). Zeta potential as a function of the sonication amplitude (C), and the injection speed (D). Preparations made with PLGA of 17 kg mol−1. Data represent mean ± SD (n = 3).
