Chitosan (CS)/siRNA polyplexes have great therapeutic potential for treating multiple diseases by gene silencing. However, clinical application of this technology requires the development of concentrated, hemocompatible, pH neutral formulations for safe and efficient administration. In this study we evaluate physicochemical properties of chitosan polyplexes in various buffers at increasing ionic strengths, to identify conditions for freeze-drying and rehydration at higher doses of uncoated or...
