Effect of formulation variables on size distribution and surface charge of PLGA/Eudragit RL NPs.
Notes: Influence of (A) PVA concentration and (B) organic phase and aqueous phase ratio on the particle diameter and surface charge of PLGA/Eudragit RL (50:50) NPs. Influence of PLGA and Eudragit RL ratio on particle size and surface charge with (C) 0.1% PVA and (D) 1.0% PVA aqueous phase.
Abbreviations: PLGA, poly(lactide-co-glycolide); NP, nanoparticle; PVA, polyvinyl alcohol.
