Encapsulation and Controlled Release of Recombinant Human Erythropoietin from Chitosan-Carrageenan Nanoparticles

Novel chitosan-carrageenan nanoparticles were produced through the process of ionotropic gelation for the encapsulation and controlled release of recombinant human erythropoietin (rHu-EPO). The effects of chitosan concentration, chitosan to carrageenan mass ratio and solution pH on the nanoparticle diameter, polydispersity and surface charge were explored through both screening and response surface modeling (RSM) methods. The...
