Chitosan is a biopolymer derived from chitin, a natural polymer found in the shells of crustaceans such as shrimp, crabs, and lobsters. It is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). Chitosan has a range of applications due to its unique physical and chemical properties, including its ability to form films, gels, and beads, and its biocompatibility.

Development of a new inhaled swellable microsphere system for the dual delivery of naringenin-loaded…
Abstract
This study developed a new dual delivery system of naringenin (NRG), a polyphenol, and doxofylline (DOX), a xanthine derivative, as an inhaled microsphere system. In this system, NRG has been first loaded into glyceryl tristearate-based solid lipid nanoparticles (NRG SLN), which were…
