A The in vitro release profile of Um from Al-MOF nanoparticles. B DPPH% scavenging activity of Al-MOF nanoparticles, Um, and conjugated Um-Al MOF nanoparticles represented by IC50 values. The results were presented as a mean and SEM. a significant versus “control”. b significant versus “Al-MOF”, c significant versus “Um” at p < 0.05
