From: Parameters influencing the size of chitosan-TPP nano- and microparticles
Surface response for influence on average hydrodynamic diameter of particles with a molar ratio of 1. (A) Response surface graph of the influence of chitosan concentration and DA on average hydrodynamic diameter; (B) Standardized Pareto chart estimating the effect of chitosan concentration, DA, and their interaction on the average hydrodynamic diameter of the particles. The blue vertical line represents the 0.05 critical value for ANOVA. All bars extending to the right of this line indicate that the effects are statistically significant at 5% significance level; X: chitosan concentration, Y: degree of acetylation, XX: interaction effect of chitosan concentration, XY: interaction effect of chitosan concentration and degree of acetylation, YY: interaction effect of degree of acetylation. (C) Interaction plot of the studied factors on the average hydrodynamic diameter of the particles.
