Nowadays, drug delivery has an important role in medical therapy. The use of biopolymers developing systems (DDSs) is increasingly attracting attention due to their remarkable and numerous advantages, contrast conventional polymers. Biopolymers have many advantages (biodegradability, biocompatibility, renewability, affordability, availability), which are extremely for materials with applications the biomedical field. Additionally, appropriate when they improve functioning a number positive...
