Amphipathic chitosans improve the physicochemical properties of siRNA-chitosan nanoparticles at physiological conditions

Chitosan has received a lot of attention as a carrier for small interfering RNA (siRNA), due to its capacity for complexation and intracellular release of these molecules. However, one of its limitations is its insolubility at neutral pH and the tendency towards aggregation of its nanoparticles in isotonic ionic strength. |
