Determination of nanoparticle stability: (A) nanoparticle diameter (z-average, nm); (B) polydispersivity index; (C) zeta potential (mV); (D) encapsulation efficiency.
Measurements were made of the formulations containing the polymeric nanocapsules and solid lipid nanoparticles, with and without the fungicides, at ambient temperature after different periods of storage (0, 15, 30, 60, 90 and 120 days). The values shown represent the averages of three determinations. The level of significance was p < 0.05 for the statistical differences observed between the groups, where the a* represents statistical differences compared to 0 day; b* compared to 15 days; c* for the 30 days; d* for the 60 days and e* for the 90 days.
