Semi-IPN chitosan/polyvinylpyrrolidone microspheres and films: sustained release and property optimisation.
TL;DR: It can be concluded that the prepared CH-PVP semi-IPN microspheres are novel promising carriers compared to pure CH micro Spheres since it becomes possible to adjust stability and hydrophilicity of the microsphere as well as the release rates of the drugs from the micro spheres by changing the ratio of CH/PVP composition.

Oral drug absorption enhancement by chitosan and its derivatives.
TL;DR: Mono-carboxymethylated chitosan (MCC) is a polyampholytic polymer, able to form visco-elastic gels in aqueous environments or with anionic macromolecules at neutral pH values, and appears to be less potent compared to the quaternized derivative.
