Chitosan-based hydrogels: Preparation, properties and applications.
TL;DR: The molecular dynamics simulation were performed on the delivery of the anticancer chlorambucil (CB) drug using three silica filled polymeric nanocomposites based on chitosan (CS), polylactic acid (PLA) and polyethylene glycol (PEG) and it was illustrated that among three drug delivery systems, the CSnanocomposite was the most efficient DDS due to the lowest drug diffusion.
