With the recent advances on the nanotechnology science, nanoencapsulation is rapidly growing. Nanocapsules are nanostructured materials composed of a core and a protective layer . The core is typically solid or liquid, and the protective layer is usually a non-toxic polymer membrane, which makes the delivery of the drug controllable. Today researchers are interested in novel drug delivery systems that are able to release drugs in a specific area without affecting other non-contaminated areas, preventing overdoses and leveraging the effect of the drug and its use in the diagnosis of the diseases as marker or contrast agent at the same time , , .
In this work, we show the nanoencapsulation of hydrophobic ION's within an oleic acid nanoemulsions using sodium dodecyl sulfate (SDS) as surfactant coated with chitosan and its characterization. Due to the properties of toxicity, biocompatibility, and biodegradability, exhibited by the materials used for the nanocapsules synthesis, is believed that they could be a good alternative to the state-of-the-art ones due to the possibilities of use the nanocapsules with the iron oxide nanoparticles within as contrast agents, thermo-therapies, and delivery vectors for bioactive ingredients.
