Its encapsulation in PLGA nanoparticles (NPs) can overcome such challenges. PLGA and PLGA-Resveratrol NPs optimal synthesis input variables were studied by fractional factorial and Box-Behnken design methodologies, respectively. It was found that PLGA NPs physicochemical properties were mainly affected by the amount of PLGA and PVA concentration. PLGA-Resveratrol NPs optimal synthesis, using as input variables the amount of PLGA, Resveratrol, and PVA concentration, yield a hydrodynamic diameter of 137 nm, polydispersity index of 0.195, drug loading of 16 %, and z-potential of-24.71 mV. These results are in very close agreement with the predicted values.
