Negatively charged chitosan nanoparticles prepared by ionotropic gelation for encapsulation of positively charged proteins

[Display omitted] The nanoprecipitation of hydrogel nanoparticles by complex coacervation is investigated through a systematic study of the popular chitosan-polyphosphate pair of polyelectrolytes with opposite charges at pH 4. Polyphosphates of varying molar masses and electrical charges are investi...
