Characterization of Nanocapsules of Sodium Alginate and Moringa oleifera Extract by AFM as a Therapeutic Alternative

Alginate nanocapsules loaded with <i>Moringa oleifera</i> extract, a plant traditionally used for its hypoglycemic properties, were developed as a therapeutic alternative for type II diabetes mellitus. The nanocapsules were obtained by manually spraying a WO emulsion with an airbrush and were stabilized in 2% calcium chloride. Characterization by atomic force microscopy revealed spherical particles with an average diameter of 10.087 nm, an area of 298.441 nm², and a density of 0.207556/nm², confirming efficient encapsulation and uniform morphology. This low-cost method is promising for the creation of controlled release systems in resource-limited settings.
