Influence of polyvinyl alcohol (PVA) concentration and aqueous phase (pH 7.5) volume on the entrapment efficiency and mean diameter of nanoparticles.
Notes: NP8: 6 mL of 0.5% PVA; NP9, NP10, and NP11: 6, 10, and 15 mL of 1.0% PVA, respectively. Analysis of variance Tukey’s test (α = 0.05): different letters indicate significant differences and * indicates that the mean is not significantly different from the other means.
