Physiological responsiveness of three nanosuspensions. A, B) SEM images of nanosuspensions (F1–F3) in pH 4.5 (A) and pH 7.4 (B) buffers. C, D) Stability of three nanosuspensions in different concentrations (w/v) of sodium chloride (NaCl) solutions (C) and fetal bovine serum (10% v/v in PBS 0.01 M) (D) at 37 °C. Data are presented as mean ± standard deviation (n = 3). Significant differences were analyzed using one‐way analysis of variance (ANOVA), followed by the Bonferroni post hoc test: ***p < 0.001, **p < 0.01, and *p < 0.05; ns: no significant difference (p > 0.05).
